WARNING
Dehumidify Equipment and Connections
The dry contact output connects to the dehumidify input on variable--speed
furnaces and fan coils. Additional dehumidification is done by controlling the
compressor. A variety of operating modes are available. The dry contact must be
configured for dehumidification in setup Option 19. See Wiring Diagrams for more
information.
Outdoor Temperature Sensor (TSTATCCSEN01--B)
Outdoor air temperature sensor is included in the box with the Thermidistat Control.
Optimum performance is obtained when an outdoor temperature sensor is used with
the Thermidistat Control. Plan installation so that 2 wires can be run from
Equipment Control Module to an outdoor location, preferably on the north side of
the house or refer to Installation Instructions included with the outdoor temperature
sensor for simplified connection. Sensor can be mounted to outdoor unit and
existing control wires may be used for its connection. Details are provided in sensor
instructions.
