Senztek SolaSmart Plus Controller to suit SolarArk systems (includes free thermal heat paste)The Senztek SolaSmart Plus is the latest model of Differential Solar Controller from Senztek. The SolaSmart Plus has all the features of the previous models (SolaStat 1-2 and 1-3) but with the addition of a smart "Top-Out" feature and element "Boost". The smart "Top-Out" has a two stage control, which allows the system to restart solar gain harvesting when the tank temperature drops below the set "Top Out" temperature, when the collector is still at stagnation temperatures. The "Boost" is a one-hit function with a smart re-set, when the target temperature is reached. The element can also be set to operate at times that best suit the household's needs, minimising electricity usage.
Solar Hot Water Parts includes heat transfer paste and joiners with this controller. We are also trialling free 5ml silicone tubes to help make replacement
Solar Hot Water Controller installation kit includes:
1 x 3m PVC Inlet Sensor
1 x 3m PVC Tank Sensor
1 x 20m Teflon/PVC Plug In Sensor including free thermal heat paste
