Consists of 2 pieces “Transmitter” and “Receiver“. The transmitter, which is also the thermostat, can be placed in the area where we want to control the temperature, either on the wall or on a piece of furniture. The receiver is placed either near the boiler we want to control (as long as it is within communication distance) or at the waiting point of the cables intended for the thermostat.

It operates with a 3/4 wire connection and can be installed directly in place of the old thermostat. It is of the latest modern technology. You can download the smart RM app for Android and iPhone via the play store or by scanning the barcode.

The thermostat (Transmitter) connects via miniUSB to a 5V USB power supply (The power supply is not included). Alternatively, it can also operate with 4 alkaline batteries.

The Receiver connects to the network (230 Volt) and provides a switching contact for the command to the boiler.

With the large LCD screen, operation control and handling are very easy.

With five modes of operation, the system can operate according to the desired temperature you have set. The time programming function allows programmable operation and unlimited 5 + 1 + 1 day programs. The smart room thermostat gives ON/OFF commands to the heating system to achieve the desired temperature.

• POWER led – green Led when the receiver is connected to the power supply it lights up steadily. If we turn off the transmitter the Led blinks.
• LOAD Led – red Led
• a. when there is no error, it lights up red steadily when the thermostat gives an ON command and is off when it does not give a command
• b. when there is an error it blinks
• b.1. in case of IP address error (i.e. receiver and transmitter have different IP addresses) it blinks 2 times every 2 sec. We need to check the IP addresses – Parameters B1 and B2 if they are the ones listed on the transmitter and receiver and re-tune the transmitter with the receiver. If the IP addresses are correct and yet the RF connection between the transmitter and receiver is intermittently lost, we need to set parameter B06 to a time greater than 25 sec, e.g. set B05 to 0 and B06 to 27 (sec). If the transmitter is powered by batteries, then set parameter B05 to a value >20 min.
• b.2. no wifi signal detected within one hour, it blinks 3 times every 2 sec.
• b.3. in sensor error, it blinks 4 times every 2 sec. Parameter B4 must be set to N1
• SIGNAL RF matching light – orange Led – blinks when the transmitter communicates with the receiver
• WIFI Signal WiFi matching light – Blue led. With the receiver in ON state, press and hold the PUSH button until the blue Led starts blinking, then we can register the thermostat in the application. Once connected to wifi the Blue Led remains steadily lit.

• Internet connection with wifi via the wireless Router
• Temperature control
• The LCD screen shows the actual room temperature, the operating mode (H/C), the WiFi signal,

• Manual or with a preset program,
• Program Features
• Weekly program, up to 48 programs per day, remote control via smartphone,
• APP available for Android 2.3 or iOS 7.0

With the application for smart RM – TUYA you can make the following settings:

• Control method: manual or preset values (time schedule)
• Setting desired temperature by 0.5 oC,
• Setting weekly program,

• The desired temperature
• The boiler status: operating or not
• The actual temperature
• The times & temperatures of the programs
