The Tech Boss industrial-type thermostat controls a three-way or four-way mixing valve and supports one actuator and a DHW circuit. It allows connection of a valve pump, an additional DHW circulation pump, and a volt-free contact for activating a heating appliance.

It includes an LCD display and boiler, valve, DHW, return, and outdoor sensors. It supports return temperature protection, weather compensation, and weekly control, as well as operation with a wired or two-position RS room thermostat. It can be connected to an ST-505 or WIFI RS module for management via eModul and is wall-mounted.
