Introduction

The thermostat can switch on your heating system at predetermined
times on different days of the week. For each day of the week, you can
set individual temperatures for 4 periods, called events. The thermostat
comes with a default schedule suitable for most installations. Unless you
change the settings, the thermostat will operate in compliance with the
default schedule. Lowering the temperature when the home is unoccu-
pied will reduce your energy costs without reducing comfort.
Furthermore, the thermostat features an adaptive function that automati-
cally changes heating period start times so as to ensure that the required
temperature is reached at the required time. After three days the adaptive
function has learned when the heating must be switched on.

First Time Settings

The first time you turn on the thermostat, time and day must be set. The
time flashes. Set the current time using the Up or Down buttons. Then
press the OK button to confirm the time. The day of the week will then
flash. Select the current day using the Up and Down buttons. Press the
OK button. The thermostat is now ready for use and will control your
heating according to the pre-programmed 4-event schedule (see Factory
Settings for Automatic 5:2 Program).

Ground Fault Circuit Interrupter (GFCI)

The thermostat has a built-in GFCI that ensures personal safety in case of
ground faults.
It is important that the GFCI is checked monthly.
Checking the GFCI
Testing can only be performed while the thermostat is calling for heat.
