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 normal 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
3 Connect the safety thermostat (normal closed) cable to the
appropriate terminals as shown in the illustration below.
