The Robertshaw Surface Mount Hot Water Thermostats are installed as Original Equipment in Commercial, Domestic Hot Water Storage Tanks and heat pumps for Australia & New Zealand, the WM & EWT ranges have been discontinued and superseded by the ST range.

The TSSTP is designed with fewer metal parts than the WM & EWT Series, employs the latest temperature control technology designed to give quicker response to temperature change. This promises more accurate Hot Water System operation and resultant energy savings

plumbonline offer the latest model in the Robertshaw ST13-70 series, solar hot water ready thermostats. Robertshaw are the market leader in the Australian market, the ST has been designed with fewer moving metal parts making it more reliable, more responsive not to mention simple to install. The ST13-70 has the additional feature of a "SOLAR AUTO RESET and OVER TEMPERATURE CONTROL". 

What does the auto reset do?

In simple terms the solar auto reset enables your solar hot water system either flat plate or evacuated tubes to generate as much solar heated water as possible. It does this by "cutting out" the electric element booster so the sun can generate the hot water, when the sun goes down and you use the stored hot water the Robertshaw automatically resets and allows the boosted to function as a normal electric element.    

The new ST-13 (11-33 Single element) uses the latest generation temperature control, delivering quick response as the temperature of the water stratifies in the solar hot water tank. Robertshaw's quick response saves energy maximising your investment in your solar hot water system.

Electrical safety The ST-13 (11-33 Single element) has an internal fuse protection circuit, which has been designed with solar water heaters in mind. This internal fuse is extra protection against any electrical malfunction, but it is only a one use fuse. If the fuse activates, the thermostat will need to be replaced.
