Wiring diagrams
● The thermostat is delivered with one wired bridge ① (L-Q11) for easy installation of
AC 230 V HVAC equipment (example 1).
● When loads use voltages other than AC 230 V, bridge ① must be removed before wiring
the loads to the thermostat (example 2).
● If the load current through Y2 is more than 3 A, bridge between L-Q11 cannot be used.
Adapt parameter “Q22/Q24 electrical load” in “Advanced Settings” / “Optimization”.
● For application with higher currents (Y1 > 3 A or Y2 > 2 A), adapting parameter
“Q22/Q24 electrical load” in “Advanced Settings” / “Optimization” accordingly is recom-
mended.
