Remko WP L/W Monobloc heat pump LWM 150 GRAPHIT Duo 262184

LWM Duo air/water monobloc heat pump for heating/cooling and hot water operation. Consisting of 2 heat pumps controlled as a cascade. Housing in an attractive design in combination with sound insulation and a silver-painted sheet steel front (RAL 9006). Air guide fins Designline graphite (RAL 7022). Fully hermetic refrigerant circuit with LOW-GWP refrigerant R 454B, with filter, receiver, scroll compressor and electronic expansion valve. High-efficiency controlled heating circuit pump, plate heat exchanger and electrical flow monitor. Microprocessor-controlled heat output regulation by means of an externally installed Smart Control.

REMKO Smart-Control Touch
All functions of the heat pump and the heating circuits can be set using the Smart Control touch display. The intuitive controller software with plain text menu and commissioning wizard makes installation, maintenance and integration of additional modules easier for the installer.
Control of one unmixed and two mixed heating circuits (floor or radiators) with different flow temperatures, DHW preparation and temperature control can be realised. Depending on the system version, the required I/O module is supplied in the indoor module with an enamelled DHW cylinder (300 l) or in an attractive surface-mounted housing with cable entries. The 4.3’ touch display with WLAN function is supplied in a separate surface-mounted housing and can also be installed flexibly in other rooms. Dew point control is possible via a separately installed humidity/temperature sensor. This is required for temperature control, e.g. cooling via a floor circuit. We recommend installing an additional dew point monitor (Remko EDP no. 259070) when temperature control is activated via panel heating systems.
