Domestic hot water immersion heater
As the Ecodan can recover a domestic hot water cylinder to 55°C precautions should be made to raise the
temperature to 60°C or 65
o
C dependant on DIP SW2-6 periodically for pasteurisation.
This is carried out automatically with the immersion heater energised via a relay box which in turn is powered by
FTC2. The frequency of the immersion heaters occurrence is determined by DIP switch settings SW2-4 and SW2
-5. Please note the larger the temperature rise completed by the immersion heater and the more frequently it
occurs the less efficient the system becomes.
