A frequent mode of operation for solid fuel boilers is bivalent operation with a condensing boiler. In this context, an exhaust gas temperature monitor must ensure that, respectively, only one system is used for energy generation.
The JUMO heatTHERM-AT thermostat is used as an exhaust gas temperature monitor (ATW) for accurate measurement of the exhaust gas temperature and reliable switch-off. It is optimally designed for the new boiler types. If during bivalent operation of a solid fuel boiler and a condensing boiler, an exhaust gas temperature of 80 °C is reached, the condensing boiler will be blocked by means of the ATW.
