Configuring the Thermostat
The first step after installing the Legacy Line Wi- -Fi Thermostat is to
configure the settings for the various devices (such as a furnace or air
conditioner) that are being connected.
Equipment
The Equipment settings let you configure the devices connected to the
thermostat.
To configure the equipment settings:
From the Home screen, press MENU.
Select Settings " Installation Settings.
Select Equipment.
Configure the devices connected to the thermostat.
Heat Pump
This section lets you configure a heat pump with up to 2 heat/2 cool
stages plus an auxiliary heat source.
Geothermal heat pump Select Yes if you are using a geothermal
d
heat pump. This helps the thermostat determine optimum perfor-
mance and default settings. If you select No, the system will opti-
mize the settings for an air- -to- -air heat pump.
OB energize on cool If you choose Yes, the reversing valve out-
d
put (O/B terminal) will activate when there is a call for cooling. If
you select No, the relay will activate when there is call for heat.
Min Cycle Off Time Configures the minimum compressor off
d
time between cycles (240 to 900 seconds).
Min Outdoor Temp Disables the compressor when the outside
d
air temperature reaches the configured minimum setting. This
performs two functions. It prevents the compressor from running
when the outdoor temperature is too low, thus resulting in dam-
age to the compressor. You can also set this value to determine
when you want the auxiliary heat (if installed) to engage to help
