Powering the Comfort Control

The Comfort Control can be powered with 24 Vac.

24 Vac Common Power (Recommended)

Wire the common side of the transformer to the B screw
of the comfort control wallplate. When installing in a single
transformer system, keep the jumper wire between the R
and Rc screws. When installing in a two-transformer
system, use the common from the cooling transformer to
connect to the B screw and remove the jumper wire
between the R and Rc screws.

Battery Power (Optional)

CAUTION

Equipment or Property Damage Hazard.
Using battery power only may not provide
adequate power to comfort control and can
cause damage during freezing conditions.

Connect the 24 Vac Common (B) wire from the
system transformer to the comfort control for
proper operation when the battery power is
drained.

Pub. No. 18-HD25D19-3
69-1790—3 8

Three AAA alkaline batteries can be used to power the
comfort control for armchair programming only. To prevent
the comfort control and heating/cooling system from
shutting down due to lack of battery power, it is not
recommended that the comfort control be solely powered
with the three AAA batteries during normal system
operation. When using batteries, make sure positive and
negative terminals are oriented correctly, as marked on
the device. See Fig. 16.

Cool: controls cooling system.
Auto: automatically changes between heating and cooling
systems, depending on indoor temperature. (See Installer

FAN SETTINGS

The Fan setting can be programmed into the comfort
control schedule for each period (Wake, Leave, Return,

LED Indication (Requires 24 Vac Common
Connection)

An LED indicator is located in the upper right corner of the
comfort control. It is only visible when lighted:

• It indicates when the comfort control is in the
Emergency Heat mode. When in Em. Ht. mode, the F
terminal is continuously energized and the LED is on.

• When the F terminal is wired to an equipment monitor,
the LED signals when a check or fail signal is sent to
the comfort control from the system. See Fig. 20. (This
can occur only when the comfort control is not in Em.
Ht. mode.)

ADVANCED FEATURES

Outdoor or Indoor Temperature Sensor

For accuracy, the initial reading of the indoor and outdoor
temperature sensors require five minutes to stabilize. See
the Sensor instructions for installation information.

Special Heat Pump Features

Heat Pump with Fossil Fuel Auxiliary Heat (Dual
Fuel) and Outdoor Temperature Sensor

In this operation there is no external fossil fuel kit (dual
fuel kit) installed; the comfort control controls this function.

1. Choose correct heat pump application in Installer
Setup Number 0170.

2. Choose Fossil Fuel Option as the backup heat
source in Installer Setup Number 0200.

3. Choose No External Fossil Fuel Kit Option as
controlling backup heat in installer Setup Number

0210.

4. Outdoor Temperature Sensor for Control Option
is automatically chosen in Installer Setup Number

0340.

5. Choose appropriate Balance Point Temperature
in Installer Setup Number 0350.

OPERATION IN HEAT MODE ABOVE BALANCE POINT
(OUTDOOR TEMPERATURE)

When the outdoor temperature is above the selected
Balance Point Temperature (ISU 0350), only the
compressor operates and the fan (G terminal) energizes
when the comfort control calls for heat.

OPERATION IN HEAT MODE BELOW BALANCE POINT
(OUTDOOR TEMPERATURE)

When the outdoor temperature is below the selected
Balance Point Temperature (ISU 0350), only the Fossil
Fuel (auxiliary heat) operates and the fan (G terminal)
does not energize when the comfort control calls for heat.

OPERATION IN EMERGENCY HEAT MODE

The balance point (outside) temperature is not used in the
Emergency heat mode. When the comfort control is
moved to the Emergency Heat position, the compressor is
locked out. The first stage of heat is whatever is
connected to the X2 terminal. The second stage of heat is
what is connected to the W1 terminal. Often there is only
one source of non-compressor heat and the X2 terminal is
jumpered to the W1 terminal.

Heat Pump with Electric Auxiliary (Backup) Heat
and Outdoor Temperature Sensor

1. Choose correct heat pump application in Installer
Setup Number 0170.

2. Choose Electric as Auxiliary (Backup) Heat
Source in Installer Setup Number 0200.

3. Choose Outdoor Temperature Sensor for
Control Option in Installer Setup Number 0340.

4. Choose Compressor Lockout Temperature in

Installer Setup Number 0350.

5. Choose Auxiliary Lockout Temperature in
Installer Setup Number 0360.

NOTE: There is a 5°F deadband between the Compres-

sor and Auxiliary Heat Lockout Temperatures

OPERATION IN HEAT MODE

When the outdoor temperature is below the Compressor
Lockout Temperature, only the Auxiliary Heat operates.

When the outdoor temperature is above the Auxiliary
Lockout Temperature, only the Compressor operates.
See Fig. 21.

OPERATION IN THE EMERGENCY HEAT MODE

Once the comfort control is placed into the Emergency
Heat mode, the compressor and auxiliary lockout features
are turned off. In the Emergency heat mode, the
compressor is locked out. The first stage of heat is
whatever is connected to the X2 terminal. The second
stage of heat is connected to the W1 terminal. Usually the
emergency and auxiliary heat sources are electric strip
heat in these cases.

Dehumidification Droop Control

The dehumidification control attempts to control to the
user's humidity setpoint by turning on the air conditioner.
In extremely high humidity conditions, the comfort control
keeps the air conditioner running for up to 3
temperature setpoint. It does this while trying to achieve
the desired humidity setpoint and balancing that with the
temperature setpoint.
