OPTIONAL OUTDOOR THERMOSTAT
APPLICATIONS
Since most equipment at the time of manufacture is not
designated for any specific destination of the country and
are installed in areas not approaching the lower outdoor
temperature range, outdoor thermostats are not factory
installed as standard equipment, but are offered as an
option. There are also different applications for applying
outdoor thermostats. The set point of either type of
outdoor thermostat application is variable with
geographic region and sizing of the heating equipment
to the individual structure. Utilization of the heating
Application Data, and the heat loss calculation of the
building are useful in determining the correct set points.
Temperature and Humidity Controller #8403-060, along
with the Outdoor Sensor option Part #8403-061, can be
used to:
• Limit minimum outdoor temperature for cooling option.
• Limit minimum outdoor temperature for heat pump option.
• Inhibit electric heat operation for heat pumps above
selected outdoor temperature.
Thus, not requiring the optional compressor cut-off
thermostat or the electric heat cut-off thermostat option.
