CONSIDERATIONS

Models
There are four models in the Comfort Series: programmable
and
non-programmable, AC and HR Models TC-PAC and TC-NAC are designed for
AC systems, controlling one stage of cooling and one stage of heating. They will not
operate a heat pump. Models TC-PHP and TC-NHP are designed for HP systems,
controlling one stage of cooling and two stages of heating. They can be converted to
AC operation. Select the appropriate model for the intended application.
Power
All Comfort Series models are dual powered. They can operate from batteries or
24VAC power. Operation from 24VAC is preferred if available. Battery

operation is used when there are not enough
or when "armchair
programming"
is desired.

wires to support 24VAC operation
For an AC system, up to six wires

are needed for 24VAC operation
and one less wire for battery operation.
For a
HP system, up to seven wires are needed for 24VAC operation and one less wire
would be sufficient for battery operation. For heat only operation with batteries,
only two wires are required.

Option 04 - Fan (G) ON with W output
Selections:
OF = G not energized with W -- This is default.
ON = G energized with W.
This selection determines whether the fan (G) is to be ON or OFF when the W
(furnace or strip heat) is ON. Furnaces and fan coils which manage their own
blowers do not require a separate G signal. Some auxiliary heaters require a
separate G signal to operate the blower when W is applied.
Option 07 - Zoning
Selections:
OF = non-zoned

system -- This is default.

ON = zoned system.
ON disables thermostat's internal timers which are not needed with zoning
system controls. Must be set to OF for non-zoned systems.
Option 10 - Reversing valve
This selection is only available on heat pump systems. "O" terminal can be
configured to be energized in either heating mode or in cooling mode, depending
on heat pump operation. :'O" is used to describe a heat pump system that
energizes its reversing valve in cooling. :'B" is used to describe a heat pump
system that energizes its reversing valve in heating.
