Humidistat or Outdoor Thermostat
AdjustingThermostatAnticipator
Set the heat anticipator of the thermostat to the proper value. See
instructions provided with the thermostat before making this
adjustment.
Adding Humidistator Outdoor Thermostat
Adding a humidistat or outdoor thermostat allows the airflow to be
reduced to 80% of normal allowing greater humidity control.
Humidistats are preferred but an outdoor thermostat can be used
but can only be set based on temperature. Suggested starting
point is 85 °F, but this will vary depending on several factors.
The control must be wired differently on air conditioners and heat
pumps. On air conditioners connect to Y and H (Dehum)
terminals, ref Figure 7.
HEAT PUMPS ONLY: Heat pumps must use only the outdoor
thermostat, because it is powered instead of just performing a
switching function. This allows it to be out of the circuit when
continuous circulation is desired, which is required for the system
to operate on Fan Only for circulation, which is 60% airflow. On
heat pumps connect to Y and H (Dehum) terminals, and C and O
to power the outdoor thermostat, ref Figure 8.
ElectricHeaterStaging
The heater elements are turned on in increments. Refer to Heater
Staging Table in the Heater installation Manual. In addition on
heaters larger than 5KW, the heat can be staged (1 st & 2nd) either
through an indoor thermostat or by using an outdoor thermostat.
This satisfies staging requirements imposed by some electric
utilities on heaters larger than 6 kilowatts.
A control signal (24V) from Wl on the Indoor T'stat to Wl on the
control board energizes the 1st stage of heat. A control signal
(24V) to W2 on the control board energizes the second stage of
electric heat. To turn ON both stages atthe same time, using one
control signal, W1 and W2 are jumpered together.
If the indoor thermostat does not have staging capabilities,
accessory electronic outdoor thermostats are available that will
control two stages of electric heat.
MotorSpeedsandAirflow
See Figure g and Pages 8 & g,
The motor speed can be set on one of eight speeds and the air
flow will adjust between 60%, 80% and 100% depending on
settings. Time ON /OFF settings can also be adjusted.
Determine coil static pressure drop, consult coil manual and
measure duct system static pressure, then determine required
speed setting from blower charts.
For Cooling - Set switches 6, 7, and 8 on the motor end bell to
position 0 (off) or 1 (on) as specified on blower charts.
For Heating - Set switches 3, 4, and 5 on the motor end bell to
position 0 (off) or 1 (on) as specified on blower charts.
Set switches 1 and 2 to position 0 (off) or 1 (on) as specified in
Figure 9 to control Fan delay ON - OFR
NOTE: Power must be completely OFF to unit any time
switch settings are changed or settings will not take effect.

Air Flow Check
For proper system operation, the air flow through the indoor coil
should be between 350 and 450 cfm per ton of cooling capacity.
The air flow through the unit can be determined by measuring the
external static pressure to the unit and selecting the motor speed
tap that will most closely provide the required air flow.
1. Set up to measure external static pressure at the supply
and return duct connections (Figure 10).
2. Drill holes in the ducts for pressure taps, pitot tubes, or
other accurate pressure sensing devices.
Figuie ! 0 J

Indoor
Section
Static Pressure Check
_?
3. Connect these taps to a level inclined manometer or draft
gauge.
4. Ensure the coil and filter are clean, and all the registers are
open.
5. Determine the external static pressure with the blower
operating.
6. Refer to the Air Flow Data tables, page 8 to find the Dip
Switch Speed setting that will most closely provide the
required air flow for the system.
7. Refer to Motor Speeds and Airflow in these instructions if
the speed is to be changed.
8. Recheck the external static pressure with the new setting,
and confirm speed switch selection.
TemperatureRiseCheck
Temperature rise is the difference between the supply and return
air temperatures.
NOTE: The temperature rise can be adjusted by changing the
heating speed tap at the unit's blower terminal block.
A temperature rise greater than 60 OF (33.3 °C) is not
recommended.
1. To check the temperature rise through the unit, place
thermometers in the supply and return air ducts as close to
the unit as possible.
2. Open ALL registers and duct dampers.
3. Set thermostat Heat-Cool selector to HEAT.
4. Set the thermostat temperature setting as high as it wil! go.
5. Turn electric power ON.
6. Operate unit AT LEAST 5 minutes, then check
temperature rise.
NOTE: The maximum outlet air temperature for all models
is 200 OF (93.3 °C).
7. Set thermostat to normal temperature setting.
8. Turn electric power OFE
9. Be sure to seal all holes in ducts if any were created during
this process.
Maintenance
Filters
Filters must be cleaned when they become dirty. Inspect at least
once per month. The frequency of cleaning depends upon the
hours of operation and the local atmospheric conditions. Clean
filters keep unit efficiency high.
Lubrication
The bearings of the blower motor are permanently lubricated.
Condensate Drains
During the cooling season check the condensate drain lines to be
sure that condensate is flowing from the primary drain but not
from the secondary drain. If condensate ever flows from the
secondary drain the unit should be promptly shut off and the
condensate pan and drains cleaned to insure a free flowing
primary drain.
