8.12. Cold Side Anti-Freeze (Recovery/Source)
The cold side anti-freeze is managed by parameters AI09-AI16. The reference probe for

cold water side anti-freeze heater on the outlet probe reading. If the water outlet probe is in
alarm, the anti-freeze heater is adjusted by parameters AI11 and AI12 on the inlet probe
reading.
Parameters AI13 and AI14 regulate activation of the cold water side anti-freeze alarm on the
outlet probe reading. If the water outlet probe is in alarm, the anti-freeze alarm is adjusted by
parameters AI15 and AI16 on the inlet probe reading.
