kotech's room temperature control system
Will lead the way in developing new technologies for a new heating culture.
Centralized Control System
Centralized Control System

This is Kotech's Control System with the least installation cost.
Instead of installing a temperature controller in each room, the heating status of all rooms is checked from the living room, and heating is controlled by time.
Its functions include heating/stop modes and 24-hour time reservation for each room.
