203GT

Heating 
regulator

203GT 

is a new generation heating regulator.  

Its versatility, intelligence and clarity have made it 
an ideal heating regulator for all kinds of water 
circulation heating systems.

In addition to heating control, 203GT has a 
number of other control and alarm functions 
for facilities.
 
Measurement information can be read, settings 
and controls can be checked and adjusted, 
and alarms can be received and acknowledged 
remotely via a GSM telephone’s text messages. 
A GSM modem (optional equipment) must be 
connected to  203GT to enable GSM use.
