Equipment The Equipment settings let you configure the devices connected to the thermostat. To configure the equipment settings: From the Home screen, press MENU. Select Settings " Installation Settings. Select Equipment. Configure the devices connected to the thermostat. Heat Pump This section lets you configure a heat pump with up to 2 heat/2 cool stages plus an auxiliary heat source. Geothermal heat pump Select Yes if you are using a geothermal heat pump. This helps the thermostat determine optimum performance and default settings. If you select No, the system will optimize the settings for an air--to--air heat pump. OB energize on cool If you choose Yes, the reversing valve output (O/B terminal) will activate when there is a call for cooling. If you select No, the relay will activate when there is call for heat. Min Cycle Off Time Configures the minimum compressor off time between cycles (240 to 900 seconds). Min Outdoor Temp Disables the compressor when the outside air temperature reaches the configured minimum setting. This performs two functions. It prevents the compressor from running when the outdoor temperature is too low, thus resulting in damage to the compressor. You can also set this value to determine when you want the auxiliary heat (if installed) to engage to help 23 d meet the set temperature. The temperature range is adjustable from 0 to 65° F (–17.8 to 18.3° C) or can be completely disabled. Note: You need an Internet connection for this feature to operate properly. Allow HP with Aux Heat If you select Yes and there is a source of auxiliary heat, it will turn on in addition to the heat pump. The heat pump will be energized for the first 30 minutes. If, after 30 minutes, the set point has not been met, the auxiliary heat will be energized to assist the heat pump in meeting the load. If you select No, the heat pump will be energized for up to 2 hours. If after 2 hours the set point has not been met, the thermostat will shutdown the heat pump and energize the auxiliary heat to meet the set point. This option should also be used for installation where the heat pump evaporator coil is upstream from the source of auxiliary heat. This setting is only available when the Comp to Aux Temp Delta and Comp to Aux Runtime settings are both set to Auto (default). Furnace Allows you to enable and configure up to a 2--stage conventional heat source. If you have selected a heat pump as your primary source, this feature allows you to configure the 1st stage of auxiliary heat connected to the system. Furnace Type Allows you to configure the type of furnace. This helps the thermostat optimize its algorithms based on the type of fuel and typical characteristics of the chosen system. Choose the option that best represents the type of heating system installed. Heat Fan Control Configures the furnace fan to be controlled by the thermostat or the HVAC system during heat cycles. Normally the HVAC system controls the fan during heat cycles. Air Conditioner Configures up to 2 stages of air conditioning. If you require a second stage, you must enable the Y2 relay. 24 Thresholds This section configures the temperature and time thresholds associated with the heating and cooling equipment. You must configure the Equipment settings (page 22) before setting the thresholds. Only the applicable threshold settings will be displayed (i.e. if no air conditioner is configured, you will not see the options related to air conditioners). To configure threshold settings: From the Home screen, press MENU. Select Settings " Installation Settings. Select Thresholds. Configure the temperature threshold settings. Allow Auto Heat/Cool Enabling this option allows the user to select auto change--over as a system mode. Heat/Cool Min Delta The minimum difference between the heat mode set temperature and the cool mode set temperature when the system mode is in auto change--over. The delta is adjustable from 2 to 10° F (1.1 to 5.5° C). The default value is 5° F (2.8° C). Compressor Settings Min Cycle Off Time Configures the compressor off time between cycles. This ensures the compressor does not short cycle (which could affect the operating life of the system). This time is adjustable from 240–900 seconds. Min Outdoor Temp Configures the minimum outside air temperature at which the compressor will be disabled. This performs two functions. It prevents the compressor from running when the outdoor temperature is too low, thus resulting in damage to the compressor. You can also set this value to determine when you 25 want the auxiliary heat (if installed) to engage to help meet the set temperature. The temperature range is adjustable from 0 to 65° F (–17.8 to 18.3° C) or can be completely disabled. Note: You need an Internet connection for this feature to operate properly. Aux Heat Settings Max Outdoor Temperature Configures the maximum outdoor temperature threshold. Above this level, the auxiliary heat will not be activated. The temperature is adjustable from 0 to 80° F (26.5° C) in increments of 0.5° F (0.3° C). The default value is 70° F (21° C). Common Heat/Cool Settings Heat Differential Temp The minimum difference between the current temperature and set temperature before the system calls for heat. A smaller difference means shorter cycle times, whereas a larger difference results in longer cycle times. The temperature range is adjustable from 0 to 3° F (--17.5 to 26.5° C) in 0.5° F (0.3° C) increments. Heat Dissipation Time The amount of time the fan will run after the heat set point has been reached and the call for heat has been turned off. Running the fan for a period of time allows for any heated air left in the ducts to circulate throughout the home. The time is adjustable from 0 to 900 seconds. The default value is 30 seconds. Cool Differential Temp The minimum difference between the current temperature and set temperature before the system calls for cool. A smaller difference means shorter cycle times, whereas a larger difference results in longer cycle times. The temperature range is adjustable from 0 to 3° F (0.3 to 1.7° C) in 0.5° F (0.3° C) increments. Cool Dissipation Time The amount of time the fan will run after the cool has been turned off. Running the fan for a period of time allows for any cooled air left in the ducts to circulate throughout the home. The time is adjustable from 0 to 900 seconds. The default value is 30 seconds. 26 Advanced Settings These options customize how long each stage will run before the next stage turns on. You may also program when a particular stage is turned on based on the temperature delta between the set temperature and the current temperature. d Reverse Staging If enabled, the thermostat will cycle down from the higher stages so that when it approaches set point it will only be running in stage 1. The thermostat calculates which stage to start the HVAC equipment in depending on the indoor temperature and set point temperature delta. The HVAC equipment will start in stage 1. As the stage 1 temperature delta is exceeded, the second stage will engage. Once the equipment has brought the current temperature back to within the heat or cool differential setting, stage 2 will disengage and stage 1 will remain running until the set point is met. d Stage 2 Temp Delta The minimum difference between the current temperature and the set temperature that will activate the auxiliary heat (regardless if the maximum run time of the previous stage was reached). Options are Auto (default) and 1 to 10° F (0.6 to 5.6° C). d Stage 1 Max Runtime The maximum amount of time stage 1 will run before engaging the next stage. Options are Auto (default) and 10 to 120 minutes. d Comp to Aux Runtime The maximum amount of time this stage will run before engaging the next stage. Options are Auto (default) and 1 to 10° F (0.6 to 5.6° C). d Comp to Aux Temp Delta The minimum difference between the current temperature and the set temperature that will activate this stage (regardless if the maximum run time of the previous stage was reached). Options are Auto (default), Disabled, and 1 to 10° F (0.6 to 5.6° C). d Cool Min On Time Sets the minimum equipment run time in cool mode: 1 to 20 min (default is 5 min). d Heat Min On Time Sets the minimum equipment run time in heat mode: 1 to 20 min (default is 5 min). 27 Temp Correction Lets you program an offset between the real temperature at thermostat and the displayed temperature. If you find that the temperature where the thermostat is located does not represent the room temperature, change the offset to compensate for the difference. The correct temperature is adjustable from +/-- 10° F in 0.5° F (0.3° C) increments. Installer Code To prevent accidental modifications to the installation settings, you can enable a 4--digit installer code. This code is pre--programmed to 3262.
