INSTALLATION
The H32 Control is a three (3) zone control panel that can be
used with conventional single stage, two stage heating and
cooling and heat pumps with or without dual fuel and two
speed heat pumps for up to three stages of heating. The
H32 panel is the central control panel that all zone dampers,
zone thermostats, HVAC Equipment Controls, power
transformer, Outdoor Air (OAS) and Leaving Air Sensor (ZPS)
are wired.
When installing the H32 panel it is important to pick a
central location where it is most convenient to bring all the
wires. Most often this is at 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 panel can be located in an attic
space or in an enclosed cabinet of a rooftop unit. Insure the
panel is not in direct exposure to the elements.
The cover easily removes from the case by pulling firmly and
separating the cover from the case exposing the circuit
