1. Specifications
This chapter explains how the clock thermostat
and some of its functions work.
• No batteries.
• Loss of voltage
• Manual mode
• Central heating’s clock program.
• Self-learning switch-on optimization: Comfortably warm on
time.
• Additional savings in Economy setting.
• On-screen device information.
• Modulating central heating control.
• Weather dependent control.
• Timer function.
No batteries
For its functioning the clock thermostat receives its energy
from the connected boiler. No batteries required.
Loss of voltage
In the case of loss of voltage all settings are saved in the clock
thermostat’s memory. After a 4 hour loss of voltage only the
day and time setting has to be reset. However, for it to work the
clock thermostat should have been connected for a minimum
of 1 hour. To save energy during loss of voltage no information
is being displayed on the screen.
Operational mode selection:
a. Manual mode
The clock thermostat can be used as an ‘ordinary’ room ther-
mostat, i.e. without using the clock program. In this case you
can switch on the thermostat in the morning, adjust it during
the day as required and reset it to the night temperature in the
evening.
Refer to chapter 3 for additional information.
b. Automatic mode
(Clock program for central heating)
The thermostat has a clock program which automatically con-
trols room temperature every day of the week. Every day and
every half an hour a different temperature can be preset.
Refer to chapter 4 for additional information.
