8.11. Hot Side Anti-Freeze
The hot side anti-freeze function is managed by parameters AI01-AI08. Parameter AI01 is used
to select on which probe (external air or water inlet) the hot side anti-freeze heaters and the
anti-freeze alarm are activated. Parameter AI02 is used to select whether to activate the
hot side anti-freeze heater and forced hot water circulation for anti-freeze protection. If
parameter AI02 = 1 (ON), the external air probe or utility water inlet value (depending on
parameter AI01) is compared with the difference between the values of parameters AI03 and
AI04. With values lower than (AI03-AI04), the anti-freeze heater is activated and pump
circulation is forced at a speed no lower than parameter AI05. The
icon is displayed. When
the temperature rises above the value of parameter AI03, the heater is switched off and the
pump resumes the speed set by the regulation.
