Q: How to activate LMT license

Q: Why is the high pressure switch active? (alarm number 600) Type: Warning. Name: Hi pres. Check hot side pump/overflow valve on high temperature side. Check if there is air in the hot side water. Check is the filter is blocked on the hot side.

The unit restarts when the pressure drops below high pressure switch low-limir again. After 3rd cut-out the alarm must be ackknowledged to start the unit again.


Q: Why is the low pressure switch active? (alarm number 601) Type: Critical. Name: Low pres. Check refrigerant charge, expansion valve and evaporator for ice. Check fan for obstacles on the air to water evaporator.

The alarm must be ackknowledge to start the unit again.



Q: Why is the brine pressure low? - the brine pressure switch is active (alarm number 602) Type: Critical. Name: Leakage. Check leakage of the brine system.

The alarm must be acknowledge to start the unit again.


Q: Why is the high pressure switch repeatedly active? (alarm number 603) Type: Critical. Name Hi pres. Check hot side pump/overflow on high temperature side.

The alarm must be ackknowledge to start the unit again.


Q: Why is the temperature too low? (alarm number 604) - state freeze protect. Type: Warning. Name: Frost protection. Heat pump and electrical heater running full capacity. Check that setting are not turned off.
