A. Initial setting, wiring
1. Wiring
On the back side, in the right top corner there are 3 wiring contacts marked L (live), H (heat) and C (cool). L is wired to
control voltage (e.g. a phase), H serves for heating control, C is wired to A/C (cooling).
2. Mounting
Fix the thermostat into a suitable position by means of the enclosed screws and sockets.
3. Operation mode selector (5)
For heating control slide the selector to its right position (flame symbol), for A/C control to its left position (snowflake
symbol). The middle position means OFF.
4. Delay switch (back side, under wiring contacts)
Use the two-position switch to set the delay in turning on the heating appliance (delay = quick temperature fluctuations
do not cause the thermostat to switch on/o repeatedly):
HEAT COOL
NO DELAY 10 sec 5min
DELAY 5min 5min
The delay prevents frequent thermostat switching during temperature fluctuations.
