Two modes of boiler circulating pump -
„CH Priority"
and
„DHW Priority“
If the installation for heating the
building has only one circulating pump that drives
water not only from the boiler to the water heater but
also to the entire heating system, and then you need
to use the CH Priority mode. In such case, in order to
activate the pump the boiler must be sufficiently hot. If
you have separate pumps for the boiler and the
heating system, you should use the DHW Priority
mode. Then the pump will turn on only if there is
necessary temperature difference between the boiler
and the water heater.
Automatic switch to mode Anti-Legionella if the water heater has not been heated for seven days to a
temperature above 70°C
Capacity for backup power by UPS device.
Automatic discharge system extracting heat from the water heater at night to prevent the heat source (solar
collector) from overheating the next day, if you are away from home longer and not using enough hot water.
Timers to setup intervals of four hours for intense heat by the electric heater. Each interval can be set in any
day of the week to switch on and to what temperature water can be heated.
Control of the solar collector circulation pump power depending on the temperature difference between the
collector and the water heater.
Selection option which thermal sensor can switch on the electric heater: The one that is down near the heater
or the one in the middle of the water heater.
Prevention of freezing for the water heater and the solar collector.
Audible alarm.
Diagnosis of all thermo-sensors and display an alarm for failure.
Supports system time with date and hour.
Ability to account for consumption in kWh in digital form separately for two tariff plans.
Charts distributed by hours for the past three days providing information on electricity use in kWh and the
boiler and/or solar collectors circulation pumps.
Monitoring the heater condition and displays a message if the water is not heated.
* For water heaters with one coil (lower) the electronic unit is factory configured with what additional heat
source it may operate: solar collector or boiler.
