ST2602WIFIRF WiFi and RF programmable boiler thermostat with receiver

WiFi Smart Thermostat 230V WiFi Smart Thermostat Gas Boiler Thermostat Programmable Thermostat

WiFi Electronic Programmable Thermostat

Name: WiFi Electronic Programmable Thermostat
Brand: Smart Therm

ST2602WIFIRF is the dual protocol model: the room unit talks to the receiver over an 868.35 MHz RF link with a range of about 200 m in open terrain, and the receiver has a WiFi module built in for app control. That means the heating keeps working on the local RF link even when the internet drops, while iOS and Android apps still give remote access when the network is up.

Comparison

How It Compares

ST2602RF

ST2602WIFIRF adds a built-in WiFi module at the receiver, so the same system gains app control without losing the RF link.

WiFi only thermostats

The 868.35 MHz link keeps the room unit talking to the receiver even when the building network is down.

Use guide

Installing And Commissioning

Step 1

Mount the 86 x 86 x 26 mm receiver at the boiler on 230VAC 50 Hz

Step 2

Land the switched conductor within the 6(2)A 230V rating

Step 3

Fit 2 x AAA batteries in the room unit and confirm the RF binding

Step 4

Join the receiver to the WiFi network through the iOS or Android app

Step 5

Check the pre-set programme and adjust the calibration by up to -3 to +3
