SM Series Heat Pump6 720 220 406 (2013/1) Subject to change without prior notice

When the switch is set for Hot gas re-heat -" YES"

the unit will energize the H output on P13 when

sensing a 24 VAC input on the TB01-H. This will in

terms activate the re-heat coil for active de-

humidification.

When the switch is set to Hot gas re-heat - "NO".

the unit will disable the H terminal on P13 at all

times, when sensing a 24VAC signal on TB01-H the

unit will run the blower motor at a lower CFM in

order to have a passive dehumidification while

cooling the space.

The other DIP switch bank is used to select the

proper program in the ECM motor for the unit.

To the left of the red and green status LED’s is a

row of 1/4” male quick connects. These are used

to pass thermostat inputs on to the rest of the

control circuit. Remember to always turn off unit

power at the circuit breaker before attaching or

disconnecting any wiring from these connections

to avoid accidental short circuits that can damage

unit control components.

Do not set the ADJ DIP switch to the (-)

setting when electric heaters are installed.

Doing so may cause the heaters to cycle on

their thermal overload switches, potentially

shortening the life of the switches.

Always disconnect power before changing

jumper positions on the interface board and

reset the unit afterward.
