STARTUP AND CHECKOUT After the installation is complete, verify correct operation as follows: 1. Place the Em Heat switch in the Off (down) position. 2. Place the Zone-A-Lone switch in the Occup/Remote (up) position. 3. Verify that the DIP switches are set correctly. See Sequence of Operation section and Table 6 for correct configuration. 4. Power up the TZ-3 and set the thermostats so no zones are calling. The board then enters the Purge mode where all dampers open and the fan operates for two or three and one-half minutes (configurable). (If there is no Discharge Air Temperature Sensor connected to the 9 5. 6. 7. 8. panel, the Idle LED flashes seven times before entering the Purge mode.) Then the Idle LED turns red and each damper LED turns green. Set zone one thermostat to heat and raise the setpoint to call for heat. Verify that the heat LED is red and zone one damper remains green while the other damper LED turns red. Raise zone two setpoint to call for heat. Lower zone one setpoint to stop the call for heat to that zone. Verify that zone one LED turns red (it may be amber while moving) and zone two LED turns green. Repeat for zone three. Alternately, lower the setpoint to call for cooling.Verify that the green cool LED illuminates. 68-0223-2 TZ-3 TOTALZONE® ZONE CONTROL PANEL OPERATION Sequence of Operation Single and Multi-Stage Operation On a call for heating or cooling, the zone damper stays open to the calling zone, and the dampers close to the zones that are not calling. The TZ-3 panel brings on the heating or cooling and conditioned air is delivered to the calling zone until that zone is satisfied. When the call is satisfied, the system enters the Purge mode. This holds open the damper of the last zone calling and purges into that zone. The purge time can be set to three and one-half or two minutes. After purge, all dampers return to the Open position. The panel can control up to three stages of heating and two stages of cooling. The first stage is energized by the thermostat. The second stage of heating is brought on by the thermostat, timer, or number of zones calling. The third stage of heating is brought on by the timer or number of zones calling. The second stage of cooling is brought on by the timer or number of zones calling. Any zone thermostat can call for heating or cooling. If there are co-existing calls for heat and cool, the panel first accepts the first call. Once that call is satisfied, or a maximum of 20 minutes has elapsed, the panel switches to allow the opposite call. On a call for heating or cooling, the heat LED illuminates red or the cool LED illuminates green. The zone damper LED turns green for the zone calling, and the dampers in the zones not calling close and turn red. As AOBD dampers move, the LEDs turn amber. Purge Mode At the end of every call for heat or cool, the panel enters a Purge mode that holds open the calling zone damper for three and one-half or two minutes. During this time, the panel or the HVAC equipment can operate the fan. Purge also serves as a time delay to prevent short cycling of the heating and cooling equipment after each call. Purge LED lights to signal that the system is in the Purge mode. Pressing the purge override button for two seconds overrides the Purge mode. Unless there is a new call for heat or cool during the Purge mode, all dampers are moved to the Open position at the end of purge. DIP Switch Number Status 3 Off 3.5 minutes 3 On 2 minutes The following instructions show how to configure the panel for stage control. If the equipment is single stage, set the DIP switches as follows: DIP Switch Number Status 1 Off 5 Off 1st Stage by Thermostat, 2nd and 3rd Stages by Timer (Fig. 18) The thermostat controls the first stage of heat or cool. If the call is not satisfied by the first stage within the time set on the timer, the panel energizes the second stage. If the call for heat is not satisfied by the second stage within the time set on the timer, the panel brings on the third stage. Set the DIP switches as follows: DIP Switch Number Status 1 Off 5 Off Purge Time 15 MINUTES 20 MINUTES 10 MINUTES 25 MINUTES DIP Switch Number Status Fan Control STAGE TIMER 4 Off Panel control of fan in purge Fig. 18. Stage timer. 4 5 MINUTES On HVAC control of fan in purge Individual Zone Fan Control When all zones are satisfied, the Fan switch of each thermostat controls the fan operation for that zone. When the Fan switch is in the On position, the fan is energized, and the dampers close to zones where the Fan switch is in the Auto position. If there is a call for heat or cool during this time, the circulation mode ceases, and the heat or cool call is honored. When the zone calling is satisfied, the circulation call resumes. 68-0223-2 10 30 MINUTES M19078 1st Stage by Thermostat, 2nd Stage Heat by Thermostat The thermostat controls the first stage of heat or cool and the second stage of heat. The timer controls the second stage of cool and third stage of heat. If the first and second stages combined do not satisfy the heat call within the time specified on the timer, the panel brings on the third stage of heat. Set the DIP switches as follows: TZ-3 TOTALZONE® ZONE CONTROL PANEL . DIP Switch Number Status 1 Off stage heat using a 5-30 minute panel, or staging can be controlled by the percentage of zones calling. The O and B equipment terminals are energized for changeover use with heat pumps. 5 On Heat Pump Thermostats Stages Based On Number of Zones Calling The thermostat controls the first stage of heat or cool. The second stage of heat and cool and the third stage of heat are energized by the percentage of zones calling. See Table 4. Set the DIP switches as follows: DIP Switch Number Status 1 On 5 Off HEAT PUMP THERMOSTATS WITH SINGLE Y OUTPUT Heat pump thermostats can be used if thermostat control of 2nd stage is desired. Thermostats that have a single Y terminal for first stage heat and cool can be used. When selected, all thermostats must be similar. If the thermostat energizes O on a call for cool, DIP switch 7 must be set to On and the O thermostat wire connected to W on the thermostat connections for that zone. If the thermostat energizes B on a call for heat, DIP switch 6 must be set to On and the B wire connected to W on the panel. In either case, the O is always energized to the equipment in cooling, and the B is always energized to the equipment in heating. See Table 4 to determine the number of zones required to activate stages of equipment based on the number of zones in the system. Staging is based on the zones available in the system, not the number of zones used for the particular application. As zones satisfy, stages 2 and 3 drop out. Table 4. Staging by Percentage of Zones Calling. IMPORTANT Be sure DIP switches 6 and 7 are never both in the On position. HEAT PUMP THERMOSTATS WITH SEPARATE Y1 AND W1 TERMINALS Use heat pump thermostats with separate Y1 and W1 terminals for first stage heat and cool. Keep DIP switches 6 and 7 in the Off position when thermostat O or B wire is not used. Emergency Heat Control Number of Zones Required Number of Zones in System 2nd Stage Heat 3rd Stage Heat 2nd Stage Cool 3 2 3 2 4 2 3 3 5 2 4 3 6 3 5 4 7 3 5 4 8 3 6 5 9 4 7 5 10 4 7 6 11 4 8 6 12 5 9 7 Emergency heat is defined as using an auxiliary heat source without using the heat pump. When the Em Heat switch or a thermostat puts the panel in the emergency heat mode, the heat pump is locked out and calls for heat are sent to the E terminal. A heat pump thermostat can also control emergency heat from the thermostat system switch. An L terminal energized during the emergency heat mode is required. The recommended heat pump thermostats all have hot L terminals. See Table 1. The two stage Em heat jumper connects W2 and E. Jumper both pins to energize the W2 equipment on a call for emergency heat. When E is a different source of heat than W2, remove the jumper (for example, two-stage heat pump with electric heat strip auxiliary heat ). The jumper is located below the equipment terminals on the lower-left corner of the panel. Multi-Stage Thermostats Use multi-stage thermostats to control two stages of heat via W1 and W2 thermostat terminals. Control the third stage of heat through the stage timer built into the panel. Control the second stage of cooling with the timer. Thermostat Operation Conventional Thermostats Manual and Automatic Changeover Thermostats Conventional (R,W,Y,G) heat/cool thermostats can be used with the TZ-3 to control single or multi-stage gas, electric or oil systems and heat pumps with auxiliary heat. The panel can be configured to control second stage heat and cool and third Automatic changeover thermostats provide automatic changeover by zone. Manual changeover thermostats heat or cool based on the mode of each zone thermostat. 11 68-0223-2 TZ-3 TOTALZONE® ZONE CONTROL PANEL Rebooting Microprocessor Zone-A-Lone Switch Certain conditions can hang up the microprocessor. To reset it, press and release the Boot button. The system reboots and enters the Purge mode. When the Zone-A-Lone switch is in the occupied position and the OC/OC terminals are not used, the system functions as a normal zone control system. When switched to the unoccupied position, all dampers are opened and all requests for heat, cool, or fan, except from zone one, are not honored. The zone one thermostat becomes the controlling thermostat for the entire system. During long unoccupied periods, one thermostat can be set back instead of adjusting each zone thermostat in the building. Discharge Air Temperature Sensor The Discharge Air Temperature Sensor (not included) is a supply-duct-mounted temperature probe used to control capacity and prevent over-heating or coil-icing. The sensor attaches to the TL terminals on the panel. Set the high limit temperature on the maximum temperature dial on the panel, located left of the stage timer. See. Fig. 19. Set the temperature from 110 °F to 160°F in ten-degree increments. The recommended setting for fossil fuel/ electric systems is 160°F (default factory setting). For heat pump systems, the recommended setting is 120F. The cooling temperature limit can be set at 40°F or 48°F. 130 F 140 F 120 F 150 F 110 F Circuit Breaker Protection A built-in thermal circuit breaker protects the TotalZone panel. This circuit breaker protects the panel against shorts in the thermostat and damper wiring and the remote occupied/ unoccupied switch. It does not protect against shorts in the wiring of the HVAC equipment into the panel. When the circuit breaker is tripped, none of the LEDs illuminate and the yellow rectangular component located to the left of the TR1 and TR2 terminals is hot to the touch. Remove power to the panel for at least ten seconds to allow the circuit breaker to cool off and reset. To eliminate the short, verify the dampers and thermostat wiring. 160 F MAXIMUM TEMPERATURE The T8601D2027 and T8611G2051 include two OC terminals. When wired to the TZ-3 OC terminals, and with the Zone-ALone switch in the occupied position, the board enters the unoccupied mode during the Leave and Sleep programs. This feature requires two extra wires to the Zone 1 thermostat. M19079 Fig. 19. Maximum temperature dial. IMPORTANT Be sure the Discharge Air Temperature Sensor wiring does not run parallel with line voltage wiring unless more than 12 in. of separation exists or shielded cable is used. Fan On In Heat The system blower can be set to come on with a call for heat as required for hydro-air, heat pump, or electric heat systems. Set the blower using DIP switch 8. Use DIP switch 2 to change cooling limit settings. DIP Switch 8 Dip Switch Status Cooling Temperature Limit 2 Off 40°F 2 On 48°F Fan Control Off HVAC system On Fan on in heat TotalZone Add-A-Zone Panels If the system trips due to exceeding a high or low temperature limit, the heating or cooling system shuts down and the fan continues running to purge the conditioned air from the plenum. When the low limit is tripped, the Cool LED flashes until it resets. When the high limit is tripped, the Heat LED flashes until it resets. Once the temperature recovers by ten degrees, the equipment run resumes. Using TotalZone Add-A-Zone Panels, the system can be expanded to up to 30 zones. There are three models: TAZ-1, one zone; TAZ-2, two zone; and TAZ-3, three zone. Two wires are required to connect the TAZ to the TZ-3. IMPORTANT: When multiple panels are used, it is important that the transformers be in-phase. Check the phasing by measuring for 24V across the TR2 transformer terminals on each panel. There should be 0 Vac. If not, reverse the TR1and TR2 transformer wires on one of the panels and recheck. See Fig. 13 and the TAZ installation instructions for more information. 68-0223-2 12 TZ-3 TOTALZONE® ZONE CONTROL PANEL TROUBLESHOOTING Table 5. Troubleshooting. Symptom No LEDs are Illuminated Possible Cause Action No power to the board. Check for 24 Vac (±10%) across TR1 and TR2 Shorted wire. Check fuse.
