the furnace or air handler. It is often the most convenient location and closest to power, the HVAC unit controls and the zone dampers when typically located at or near the plenum. The H32 panel case is made of sturdy ABS plastic and can be mounted to any flat surface. It is recommended that the panel be mounted to a wall or return plenum and NOT on the furnace or plenum where it will be in contact with the excessive temperatures.
The heating limit is adjustable from 110°F to 170°F. The cooling limit is fixed at 45°F. When the ZPS senses heating above its set point, or cooling below its set point, the H32 will drop both all stages of heating or cooling. The ZPS must sense a 10°F fall for heating or rise for cooling before re-activating the first stages of heating or cooling. If two stage heating or cooling is being used the second stage timer will start again once the first stage is re-activated.
Zone Dampers – The H32 can power any 24VAC damper, either 2 wire or 3 wire. See specific wiring instructions with the damper or inside panel cover. The three damper motor contacts are for 24VAC power are COM (Common), OPN (Open) and CLS (Closed) WIRING DIAGRAM 5 - .Single Speed Compressor Heat Pump M1 M4 M6 COM OPN CLS Zone Thermostats – The thermostats wiring will be for Conventional single stage (Y-G-R-W-C) or Heat Pump (Y-G-R-E-C and O or B). See Wiring Diagram 1 and 2 for each type of thermostat.
