At the heart of HeatingSave is a four layer, a state-of-the-art, surface mount microprocessor controller with 8 temperature/light level/humidity analogue sensor inputs, 8 occupancy sensor/switch digital inputs and 8 mains relay outputs. Each relay can switch the mains (10 amps max.) or distribute mains (6 amps max.).
An additional contactor unit can switch up to 30 amps.
Each controller can have up to 16 sub-controllers, each adding 8 analogue and 8 digital inputs and 8 relay outputs.
