The device consists from the device generator (compressor, evaporator, fan, ...) and the hot
water tank. The housing of the generator is made of durable plastic and is heat and sound
isolated. The device has two attachments for air channels which enable a remote air intake
and exhaust from neighbouring rooms or the environment. The hot sanitary water tank is
equipped with a piped heat exchanger, which can be connected to an external fossil fuel,
biomass or solar energy collector powered boiler.
Hot Sanitary Water Tank
Sanitary water heater is enamelled with patented technology, heat isolated with polyurethane
and mechanically protected with sheet metal. The tank is serially equipped with a water heat
exchanger that can be connected with a boiler when choosing an additional heat source. An
Mg anode is also placed into the tank, preventing corrosion of the heater upon potential
mechanical damage to the enamel.
Electric Heater
The device is serially equipped with two electric heaters with a power of 2 x 2 kW, which
serves as an additional or backup heating source.
Along with both already installed heaters, it is possible to install an additional heater into the
hot sanitary water tank with a 6/4" attachment with separate power supply.
Anti-freeze probe
Regulator of heat pump senses the temperature of the vaporizer. In the case, that the
temperature of the vaporizer is below -
7 °C, it will perform a safety shutdown of the device for
at least 30 minutes. In such a case, the heat pumps with an electric heater automatically
switch to electric heating and the heat pumps with an attached boiler switch to boiler heating
(circulation pump switch on).
Safety thermostat
The electric heater contains a safety thermostat with a limit at 85
°C. This means that, in the
case that the temperature in hot water tank is exceeded, the power supply will be switched
off and the device will stop operating. To restart the device, call authorised installation
technician who must verify and remove the reason of the safety shutdown of the device.
WARNING
When heating with boiler or solar collectors, you may heat the water in the hot
water tank to a temperature above 80
°C whereby the safety thermostat switches
off. In such a case the thermostat has to be manually reset. To restart the
thermostat, an authorised installation technician must be called.
Boiler water temperature control
Monitoring and heating of water to desired temperature is ensured by the advanced
OPTITRONIC 2 touchscreen regulator.
In regards to the set up desired water heating temperature, the controller, as required,
switches the compressor and fan on or off, and, under certain conditions, also switches the
electric heater or circulation pump of the boiler on or off. The maximal temperature of water
heating that can be
set up is 65 °C. Should the temperature in hot water tank increase over
75
°C, the controller switches off all sources of heat for safety reasons.
Minimal temperature of water in hot water tank is 7 °C.
High pressure cooling system protection
To prevent pressure in the cooling system to get too high and potential damage, related to it,
a high pressure safety switch is installed, which stops the operation of the heat pump in the
case of pressure rising beyond a preset point.
Conditions of operation
Environment temperature must be between -
7 °C and +35 °C. The air must be clean with
relative humidity not exceeding 50% at +35
°C. At lower air temperatures, the relative air
