Description

The Steca TH A603 M is a stand-alone heating circuit controller for regulating mixed heating circuits easily and efficiently.

To limit the degree of loss as effectively as possible while ensuring the single-room control (e.g. thermostatic valve) operates optimally, the supply temperature in the heating circuit must be continuously adjusted. The necessary supply temperature is determined by the Steca TH A603 M controller based on the ambient temperature and/or the temperature of a control room and is set by the regulated mixer.

The heating circuit can be regulated on the basis of atmospheric conditions or a control room to ensure requirements are met as effectively as possible. Both radiator and surface heating circuits are available. The many functions built into the Steca TH A603 M such as surplus management, heat quantity measurement, building frost protection, holiday reduction and screed drying ensure that system operation is both reliable and convenient.

Animated control circuits are displayed on the unit's large graphic display to visualise each of the system's operating statuses. The Steca TH A603 M includes six inputs for recording temperatures or pulse values as well as an additional Grundfos Direct Sensors™ input for combined temperature and flow rate measurement. The heating circuit pump and the mixer valve are controlled via three outputs.
