- Victrix TT, Victrix Zeus, Victrix Zeus Superior (2020) and
Victrix Superior (2022) models (Fig. 6-8):
- open the connection compartment (see boiler instructions
booklet);
- remove jumper "X70";
- connect the wiring to the thermostat and to the boiler terminal
board;
- pass the wiring cables through the lower part of the connec-
tion compartment.
- All the remaining models (Fig. 7):
- access the electrical connections (see boiler instructions
booklet);
- open the control panel;
- Connect by wiring the wires as indicated in the relevant wiring
diagram.
- pass the wiring cables through the free cable clamp in the
boiler control panel.
All models:
- Remove the thermostat cover (Fig. 3) and pass the wiring
through the relative cable clamp;
- connect the wiring to the thermostat as indicated in the wiring
diagram (Fig. 6 and 7);
- re-mount the thermostat cover; close the control panel; re-
mount the casing and re-apply the voltage to the boiler to take
it back to normal functioning conditions.

ELECTRICAL CONNECTION (Fig. 6, 7 and 8)
Terminal 1 = Closes the circuit as the temperature increases.
Terminal 2 = Opens the circuit as the temperature increases.
Terminal C = Common input.
In general (central heating system), connect the user to terminals
C and 2 of the thermostat.
LOW TEMPERATURE SAFETY
THERMOSTAT INTERVENTION
During normal operation, if an anomaly causes excessive overheat-
ing of the flow temperature in low temperature conditions, the
boiler shuts down displaying error code E46 (only for Victrix TT
and Victrix Zeus), in other models the power supply is interrupted.
After suitable cooling, it is possible to reset the thermostat as de-
scribed below. If this phenomenon occurs frequently, contact a
qualified technician for assistance (e.g. Immergas After-Sales
Technical Assistance Service).
TRIGGERING TEMPERATURE RESET ANDADJUST-
MENT
To reset the thermostat, loosen the cap B and press the reset but-
ton A (Fig. 4). To adjust the triggering temperature, remove the
cover, then slightly loosen the plate locking screw and position
the plate on the desired temperature in correspondence with the
graduated scale. Tighten the plate locking screw C and reattach
the cover (Fig. 5).
