DHPi MONOTEC in a set with the DTi 200 hydraulic cabinet
is the ideal offer for users who value convenience and modern solutions. This technical solution allows all necessary hydraulic components to be installed in a single unit. Thanks to innovative engineering, the cabinet includes a controller with a touch control panel operating three heating circuits. As standard, the hydraulic cabinet features two heating circuits – one direct and one with a mixing valve – as well as a circulation pump, mixing valve, flow heater, electricity meter and overcurrent protection.
To save space in the boiler room, the hydraulic cabinet is also equipped with a 200 L domestic hot water tank, a 65 L buffer tank, two expansion vessels, and a switching valve enabling automatic redirection of hot water flow between the CH (central heating) and DHW systems. A dirt separator installed between the outdoor unit and the DTi 200 ensures safe operation of the system.
Round-the-clock control of the DHPi MONOTEC along with the hydraulic cabinet is provided by the WIFI internet module, which is included as standard.
DHPi MONOTEC – an innovative inverter heat pump
DHPi MONOTEC is a latest-generation inverter air-to-water heat pump of the PLUG IN type (quick and safe connection of the outdoor unit with the indoor unit) using PROPANE – R290 – as the working fluid. The device is dedicated to both new and modernised houses. It is also prepared for operation in cascade and hybrid systems (e.g. HEAT PUMP + PELLET BOILER). DHPi MONOTEC boasts a high COP efficiency rating and the highest energy class A+++. The correct operation of the DHPi MONOTEC inverter heat pump is directly supervised by DEFRO service.
The DHPi MONOTEC Heat Pump is available in three sales variants:
DHPi MONOTEC + DTi 200 hydraulic cabinet
DHPi MONOTEC + DFi control module
DHPi MONOTEC + DSi control module
