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.
