PARAMETER 35 - FROST PROTECTION
The third pump will start up if the outside temperature is lower than parameter 35 (Frost protection) or if the flow tem-
perature is lower than 5°C. If after 10 minutes the T1 fails to exceed 5°C, a burner will start up at maximum power until
T1 exceeds 20°C. If after 10 minutes the T4 is still below parameter 35 but T1 exceeds 5°C the pump will work until T4
exceeds parameter 35.
