Operation
Where PV heater is in operation, the relay is on.
This function could be used for example, to turn
off the primary heating during the operation of
PV heater
Main Heater
If in case of "Temperature threshold" specified
"lower" temperature is gone below, the relay
switches on.
This function could be used to turn a signal
lamp that indicates that PV heater provides not
enough hot water or to activate the primary
heating system to deliver hot water.
Solar Radiation
The relay switches on, when the "Upper" output
indicated in "Power threshold" is exceeded. The
relay turns off again, when the "Lower" output
indicated in "Power threshold" went below.
Temperature
The relay switches on, when the "Upper"
temperature indicated in "Temperature
threshold" is exceeded. The relay turns off
again, when the "Lower" temperature indicated
in "Temperature threshold" went below.
This function could be used by a consumer,
such as a washing machine that needs the hot
water, then turn on when enough hot water is
available.

"Use Enable Switch" is not set by default. This means that PV Heater starts immediately if there is
enough solar energy.
If PV Heater shall be controlled remotely, then a corresponding signal via the input X3 should be
provided (see Chapter. 5.4, page 24) and check mark should be set for "Use Enable Switch".
