Overview
The JOY HC is a room thermostat with a glass surface, three capacitive touch buttons and a 60 x 44 mm backlit LCD. It has a built-in controller for heating and cooling, with frost protection, window and door monitoring and presence, and sits in a standard 60 mm EU box. It is available in white or black and with two output arrangements: one 0 to 10 V output and two relays (AO2DO), or three 0 to 10 V outputs (3AO), with a six-way valve option. Inputs take window contacts, change-over and condensation sensors. It talks Modbus RTU on RS485 and is set up with uConfig or over the bus. Optional humidity and CO2 sensing is available on other versions; the price list units measure temperature.
