−
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
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.
