Wall Controller SAMSUNG Advanced MWR-WG01UN | Montreal, Laval, Longueuil, South Shore & North Shore

A Samsung heat pump is usually controlled with a wireless remote. That works well, until the day the remote disappears under a cushion, the batteries die in the middle of January, or several people change the settings without checking with each other. The Samsung MWR-WG01UN wired wall controller solves this by putting a complete control on the wall, in a place everyone knows. It is Samsung's advanced model, with a colour display, 7-day scheduling, dual setpoint and group control of up to 16 indoor units. At AirGreen, we install it in homes as well as in offices and businesses equipped with Samsung systems.

Central control for your Samsung indoor units

The MWR-WG01UN connects to the indoor unit by cable and takes over from the remote. It is compatible with the current RAC (residential air conditioners and heat pumps), CAC (light commercial), FJM (Free Joint Multi, multi-zone systems), DVM S (variable refrigerant flow systems) and DVM Chiller FCU fan coil ranges. This broad compatibility lets it control a large share of Samsung equipment.

One important detail: on RAC models, connecting a wired controller requires the MIM-A00UN interface board, sold separately. Our technicians check the exact model of your indoor unit before ordering and plan for this board when it is needed, so there are no surprises on installation day.

7-day scheduling

The controller lets you build a weekly schedule: a comfort temperature in the morning and evening, a lower setpoint during working hours, a different setting on weekends. In a home heated by a wall-mounted heat pump or a Samsung ducted system, this schedule cuts unnecessary run time without sacrificing comfort when you come home. In an office, it avoids heating or cooling empty rooms in the evening and on weekends.

Dual setpoint and automatic changeover

The dual setpoint lets you set separate heating and cooling temperatures. Combined with the heat pump's advanced automatic changeover, it lets the system switch from heating to cooling on its own, based on what the room needs. This is particularly useful in spring and fall in Quebec, when a cool morning is followed by a warm afternoon: the system heats in the morning, cools in the afternoon, and you have nothing to change.

Group control

A single MWR-WG01UN can control up to 16 indoor units as a group. In a store, a classroom, an open-plan office or a large basement equipped with several cassettes, this function lets you start, stop and adjust all the units in the same zone in one operation. The result: a uniform temperature and simpler management for staff.

A2L refrigerant leak alert

New generations of air conditioning systems use A2L refrigerants. The MWR-WG01UN includes an A2L refrigerant leak alert function that displays the warning sent by the system. This makes the controller a useful part of the installation's safety, in addition to being a comfort control.

Temperature measured where you live

The controller has a built-in room temperature sensor. Depending on the configuration, the system can rely on the temperature measured at the wall, at occupant height, rather than the one read at the air intake of the indoor unit, which is often installed near the ceiling. In a room where warm air collects up high, this more representative reading gives more accurate comfort.

Installation, setup and everyday use

Installing a wired controller involves the indoor unit's electronics. Our technicians first identify the range and model of your equipment, confirm compatibility and, on a RAC unit, install the MIM-A00UN board. They then choose the controller's location: an interior wall, away from direct sunlight and heat sources, at a comfortable height. The cable is routed neatly to the unit, and then the controller is configured.

Commissioning

During commissioning, we set the time, the reference sensor, the heating and cooling setpoints and, if you wish, a first weekly schedule adapted to your routine. For a group installation, we pair the indoor units involved and check that each one responds correctly. We then take a few minutes to walk you through the screen, the modes and how to change the schedule.

Tips for lowering consumption in winter

A heat pump performs best when it holds a stable temperature rather than bringing the room back up after long periods off. With the MWR-WG01UN, we recommend a moderate setback at night or while you are away, programmed in the schedule, rather than shutting the system off completely. The dual setpoint also prevents waste in the shoulder seasons by keeping the system from heating or cooling more than necessary.

Maintenance

The controller itself only needs an occasional wipe of the screen with a soft, dry cloth. Most of the maintenance concerns the indoor unit: cleaning the filters, inspecting the coil and the condensate drain. During our maintenance visits, we also check that the controller communicates properly with the system and that the schedule still matches your needs.
