Frost protection How the frost protection works:
1) Frost protection of exchanger.
The controls have a built-in protection function against preventing ice building up in
the heat exchanger.
If the exhaust air temperature falls below + 2°C for more than 1½ hours, the unit
starts to reduce the flow rate of supply air (i.e. RPM on the supply fan are reduced)
until the exhaust air temperature reaches a minimum of + 2°C. Frost protection usu-
ally starts when the outdoor air (T1) is -6 to -7°C or below.
2) Shutdown at an outside temperature below -13°C. If the outside air (T1) falls below -
13°C for more than 5 minutes, the unit will stop completely for 30 minutes. The unit
will then start up again for 5 minutes. If the temperature does not rise above -13°C,
the unit will stop again for 30 minutes, etc.
Recommendation
To ensure balanced ventilation without shutdown Dantherm Air Handling A/S recom-
mends installing pre-heat in areas where the outside temperature will fall below -6°C
for extended periods during the year.
In areas where temperatures are constantly below -13°C, pre-heat is a must to
achieve optimum operation.
