3.1. Installation
The Homcloud CTW thermostat is designed for 220-240V AC power supply and connects directly to your boiler's control wiring. It can be installed on a wall using screws or placed on a standard 503 support box (not recessed). Ensure power is off before beginning installation.

3.2. Wiring Connection
Connect the thermostat to your boiler's control circuit. The thermostat's relay contact (COM and NO/NC terminals) is independent of its power supply, offering flexibility for various boiler types. Typically, you will connect the power supply (L and N) and the boiler control wires to the appropriate terminals. Refer to the detailed wiring diagram below for correct connections.

Follow the in-app instructions to pair your thermostat with your home Wi-Fi network (2.4 GHz 802.11b/g/n). It is recommended to perform the pairing near your Wi-Fi router for the initial setup.
