Wi-Fi Module SAMSUNG MIM-H04UN | Montreal, Laval, Longueuil, South Shore & North Shore

The Samsung MIM-H04UN Wi-Fi adapter connects your Samsung heating and air conditioning system to the SmartThings app on iOS and Android. Once it is installed, you can start, stop and adjust your indoor units from your phone, wherever you are. This module is mainly intended for residential FJM multi-zone systems and Samsung commercial systems, for which it also offers group management. At AirGreen, we install it when a client wants to keep an eye on several zones or several units without having to be there.

Control your Samsung units from the SmartThings app

In the app, you find the usual settings: on/off, mode, temperature, fan speed and the position of the air louvre. The room temperature of each zone is displayed, so you can check that the house is properly heated while you are away. A 7-day schedule can be created to adapt operation automatically to your week: reduced heating during working hours, back to comfort at the end of the day, a different setting on weekends.

The app also shows daily, weekly and monthly energy consumption. These figures are provided for reference only; they are mostly useful for spotting trends and measuring the effect of a change in schedule or setpoint.

Compatibility: a point to check

In residential settings, the MIM-H04UN is designed for FJM (Free Joint Multi) systems, that is, Samsung multi-zone heat pumps. It is not suitable for single-zone wall-mounted heat pumps in the RAC range. In commercial settings, it supports single-unit light commercial systems and DVM S systems, with up to 16 indoor units per adapter. Before ordering, our technicians confirm your equipment's model so we can offer you the right module.

What it needs to work

The module requires a working Wi-Fi network at the indoor unit's location and a Samsung account. The SmartThings app is free on iOS and Android. If the Wi-Fi signal is weak in the room where the equipment is located, we will tell you during the visit so you can improve the coverage before commissioning.

Group management for commercial spaces

In an office, a store or a small building, group configuration lets you control the units of the same zone together. The manager sets the temperature of the open area or the meeting rooms once and can turn everything off at closing time, from their phone.

Installation and tips for use

Our technicians connect the adapter to the indoor unit, check communication with the system, then walk you through pairing it with the SmartThings app and your Samsung account. We give the zones clear names, set a first weekly schedule and show you where to check consumption. For a commercial system, we configure the groups according to the layout of the premises.

During the Québec winter, the app is especially useful for avoiding swings: a lower setpoint while you are away, raised an hour before you get back, is enough to limit consumption without letting the rooms cool down too much. In a cottage or an unoccupied home, the remote temperature reading lets you confirm that the heating is working.

For an FJM multi-zone system, a good practice is to give each room its own schedule: bedrooms cooler at night, the home office comfortable on weekdays only, the living room at comfort in the evening. The module needs no special maintenance. Simply keep the app up to date and let us know if you change your router or Wi-Fi password: the adapter will need to be reconnected to the new network.
