4.12 Manual heating
Description:
Electrical heater, gas or oil boiler can be as back-up devices in a solar system, this
controller can achieve constant temperature controlling, when controller gets
temperature signal of top part tank (T3) is 2
℃
below the preset temperature, back-up
heating will be triggered. When temperature of top part tank (T3) reaches to the preset
temperature, heating is ceased.
Conditions for triggering manual heating function: the setting temperature should be
2
℃
higher than tank temperature.
Activate/deactivate the function:

Under standby status,
►Press “+”“-” button can check the value of temperature sensors T0~ T4, pump speed
(
n%
), accumulative operation time of circuit pump (Hp), daily thermal energy (DKWH),
accumulative thermal energy (KWH) or (MWH).
When checking temperature, T0
– T4 will displays one by one, corresponding sensor
signal blinks.
►Press “ESC” button,
clock
and tank temperature can be displayed.
