Remote Thermostat Control
The unit is controlled by an externally mounted, remote thermostat.
The Zoneline thermostat connections provide 24 VAC only. If using a digital/electronic wall thermostat, it
must be set to the 24-VAC setting. Refer to the thermostat installation instructions for details.
Note: Some thermostats can be programmed to energize the reversing valve in heating mode or cool mode.
If the thermostat is not programmed correctly, the unit will heat when the thermostat is set to cool and cool
when the thermostat is set to heat. Refer to the instructions provided with the thermostat for thermostat
programming procedures. Also refer to the Reversing Valve section of the Components chapter for more
information.
