The L41../L61.. series aquastats are sensitive water tempera- ture control, which are provided with a liquid filled sensing sys- tem.
The following main types are available:
•Single, panel mount immersion
Aquastat with remote bulb to select the most favourable position on a boiler or vessel.
•Single, direct mounted immersion
Aquastat with insulating cover to protect against accidential touching of live parts.
•Dual, direct mounted immersion
Dual Aquastat and consisting of two basic single units, which are mounted together and protected by one common cover and using one well for the two sensors.
•Single, surface mounted
The sensor of this type is to be mounted directly on the surface of a boiler or pipe in a heating system. The Aquastat mechanism is directly attached to this sensor.
The L41../L61.. series aquastats are primarily designed for application on water filled heating systems and systems for hot water supply, mainly domestic use.
The L41../L61.. series aquastats can be divided in the following main types:
•Controller
