Daikin EKOMB28AAV1H [8/432] Frost protection
Daikin Europe NV 8
2.5.1 Frost protection
The unit is fitted with frost protection in order to prevent it from
freezing. If the temperature of the heat exchanger drops too low, the
pump will start running until the temperature of the heat exchanger
is sufficiently high. If the frost protection intervenes, code 7 will be
displayed (heating up exchanger).
If the installation (or a part thereof) can freeze, the coldest place
should be fitted with an (external) frost thermostat on the return pipe.
This must be connected in accordance with the electrical diagram
(see par. 10.2).
Note
When the unit is switched off ( - on the service display), the unit frost protection will
remain active, however a heating request from an (external) frost thermostat will be
ignored.
