Important Safety Information
•
Read carefully the information included in this manual.
•
Always switch off the main power when installing the thermostat.
•
The installation should be carried out by authorized personnel.
•
Do not use the thermostat for other applications except those that is made to be used
i.e. room heating
•
This thermostat is not an instrument. It must not be used in life critical applications.
Installation
Install the thermostat always in an inside wall in height 1.2m to 1.5m from the floor and
away of corners, positions affected of heat generating appliances, air vents , places directly
exposed to sunlight or dead air spots (e.g. behind a door, curtain etc.).
Consult the figures 1 to 6 printed at the carton box for dismantling and reassembling the
thermostat.
Before reinstall the rotating knob you can restrain the allowable adjust range by utilizing
the two plastic pins underneath.
Wiring
Connect the appropriate wires to cable terminal strip as shown in the relative wiring
diagram in the electrical connection section below.
As every electronic equipment this thermostat requires power to operate. Connect mains
phase 230VAC/50Hz to “L” and neutral to “N” terminal.
Terminals “A” and “1” comprise the potential free con
tacts of the internal relay. In case
phase control output is needed for the heating (or cooling)
system terminals “L” and “A”
must be wired together.
Operation
The
“
O-I
”
signed sliding switch of the front face activates and deactivates the thermostat.
While in on position “I” thermostat controls the heating
(or cooling) system to maintain the
desired temperature.
Adjust the rotating button to the temperature level of your choice. When temperature
differs as compared to that indicated by the rotating knob the green indicator lights on and
the contact of the internal relay closes. When the desired temperature is reached the relay
contact opens and the green indicator remains inactive.
The leftmost sliding switch of T20 type activates the domestic hot water control output
(terminal “2”) which is always
phase. At the same time the red indicator lights on.
The leftmost sliding switch of T10SW type is used to select between heating or cooling
mode. The “
” symbol indicates cooling mode and when selected the
red indicator lights
on.
This thermostat meets the accuracy and other technical specifications approximately 3
minutes after it is switched on.
