Master Therm software

Unique Master Therm software for heat pump control

Custom application for controlling the cooling circuit and peripherals Equithermal MaR (measurement and regulation) Advanced temperature feedback control in the building based on internal room temperature sensors Control via touchscreen terminal or online application Includes remote service monitoring and diagnostics Control of up to 6 heating circuits including the possibility of connecting a swimming pool or solar panel

Optional equipment selection

Master Therm Online App Advanced online control and remote service acces.

Additional pGDx touch screens (1 as standard) Parametrization, temperature compensation, humidity sensor, ethernet or wifi internet connection. Mounting possible on/in the wall (plasterboard) or in the heat pump‘s case.

Passive cooling module Exclusive for ground-to-water heat pumps. Direct heat extraction from the interior of the ground collector or borehole. Extremely economical summer cooling of the building without need for compressor work.

Water-to-water design Adaptation for use on bottom or surface water. Evaporator more resistant to sediment (coax) and different electrical equipment.

Expansion module Increases the number of regulated independent heating circuits up to 6 (from the basic 2).

Terminal pAD Temperature compensation for independent heating circuit.

Integrated electricity meter Built-in 1- or 3-phase electric meter for local measurement of electricity consumption.

Desuperheater for high efficiency hot water heating Integrated device that uses a separate hydraulic circuit to remove the heat of superheated steam at the compressor outlet and increase the efficiency of hot water preparation (heating). When the compressor is in operation (heating and cooling mode), part of its thermal energy is permanently transferred to the hot water tank.

RAL colour Individual colour for pump panels.

How it works

Ground-to-water heat pumps extract energy from the ground by means of a vertical or horizontal collector. Antifreeze circulates through the collector and removes ground heat. Thanks to the constant temperature of the ground, the heat pump has a stable source of energy throughout the year. The heat extracted from the ground is then transferred to the building. The system achieves a seasonal efficiency up to 5.5 times higher thanthat of a conventional electric boiler.
