INFORMATION
Installation of a safety thermostat (field supply) is required for the main zone,
otherwise the unit will NOT operate.
NOTICE
A safety thermostat MUST be installed on the main zone to avoid too high water
temperatures in this zone. The safety thermostat is typically a thermostatically
controlled valve with a normally closed contact. When the water temperature in the
main zone is too high, the contact will open and the user interface will show a 8H‑02
error. ONLY the main pump will stop.
Additional zone
Wires: 2×0.75 mm²
Maximum length: 50 m
Safety thermostat contact: 16 V DC detection (voltage supplied by PCB).
The voltage-free contact shall ensure the minimum applicable load of
15 V DC, 10 mA.
