About your new thermostat

Use this feature in climates where both air conditioning and heating are used on the

same day. When the system mode is in Auto, the thermostat automatically selects

heating or cooling depending on the indoor temperature.

While in the Auto mode, if a schedule override takes place (temporarily or perma-

nently) the thermostat will automatically adjust the cooling and heating settings to

maintain a 3-degree separation between the cool and heat settings.

For example, if the heat temperature is raised to where it gets within 3-dgrees of the

coolsetting,thedisplaywillshowanuparrownextto“cool”toshowthethermostat

Built-in compressor protection

This feature helps prevent damage to the

compressor in your air conditioning or heat

pump system.

Damage can occur if the compressor is

re-started too soon after shutdown. This

feature forces the compressor to wait a few

minutes before restarting.

During the wait time, the display will flash

the message CoolOn (or HeatOn if you have

a heat pump). When the safe wait time has

elapsed, the message stops flashing and the

compressor turns on.

Message flashes until safe restart

time has elapsed.
