Wi-Fi thermostat PNI CT26B for electric floor heating, 10 A, with floor sensor

Product detailed description

PNI CT26B is an embedded thermostat with Wi-Fi that monitors room temperature and turns on or off electric floor heating or the circulation pump of a heating group accordingly. You can set it directly on the panel or via your mobile device using the Tuya Smart / Smart Life app – even when you're not at home.

The thermostat operates in manual mode, where it tries to maintain the set temperature for the full 24 hours, or in automatic mode with a daily schedule. You can adjust this schedule to match your daily routine, so the heating doesn't run unnecessarily while you're at work.

The package includes the thermostat, mounting screws, and an external floor sensor. This allows you to regulate based on the air temperature in the room or the floor temperature. The black front panel made of glass and ABS plastic (86 × 86 mm, depth 35 mm) looks clean in interior design and is designed for mounting in an installation box.

Installation and compatibility

The thermostat is powered by 90–250 V AC (50/60 Hz) and its output switches 230 V AC with a maximum current of 10 A. It is suitable for electric floor heating, circulation pumps, and pump or mixing groups for floor heating, as well as 230 V electromagnetic valves. The output is a voltage-powered relay, not a voltage-free contact – if you want to use it with another device, check its manual to see what type of input it requires. The Wi-Fi module operates in the 2.4 GHz band (802.11b/g/n, WPA2 security). Connecting to 230 V should be done by a qualified electrician.

Accessories

The floor sensor is part of the package, so you don't need to buy it separately. The thermostat is mounted in the modular PNI system, so you need an installation box of the appropriate size.
