1.7
Built-in compressor protection
Your thermostat has a feature that helps prevent damage to the
compressor of your air conditioning system. Because damage can
occur if the compressor is restarted too soon after shutdown, this
feature forces the compressor to wait five minutes before restarting.
During the wait time, the message
Cool On
flashes on the screen.
When the safe wait time has elapsed, the message stops flashing
and the compressor turns on.
2.1
Using the schedule
Press the
Run
button to follow the programmed schedule. You can
have up to four periods in one day. Each period can be programmed
with a different temperature setting.
To program a period, you need to set its start time and its two
temperature settings (one when the thermostat is in cooling mode
and another one when it is in heating mode). The same period and
settings are repeated every day.
For maximum energy savings without sacrificing comfort, you can
program the schedule such that the temperature is at an economical
level when you sleep or are away during the day and at a comfortable
level when you are awake and at home.
