Saunier Duval Thermostats

Within this Saunier Duval Thermostats category we list main boiler control thermostats which are normally a secondary boiler protection device as most systems are now controlled by external thermostats, but it adds simple protection of the Saunier Duval appliance by managing the internal temperature of the boiler or appliance. Also Saunier Duval Overheat thermostats which switch the boiler off in the unlikely event of the boiler overheating. Hi and low limit thermostats which basically govern the higher and lower temperatures required for the Saunier Duval appliance. More modern Saunier Duval boilers use Thermistors or NTC Probes for electronically controlling the temperatures of both the heating and domestic hot water and Saunier Duval condensing boilers also use thermistors for monitoring flue gas temperatures.
