The factory setting for the control temperature difference is 10 ° C. P>
If the temperature difference between the two sensors exceeds the set value, the pump will start. For hot water systems, one sensor is placed on the heat sink or outlet of the solar collector and the other sensor is placed in the tank's measuring sleeve. Thus, the pump runs when the antifreeze (water) temperature of the collector can be higher than the water in the tank.
With its temperature limiter function it stops the pump at an adjustable tank temperature. The switch-off temperature is 70 ° C. We also disable this feature at the factory, but activate it when requested. P>
In direct mode, the pump can be run regardless of temperature. This function is achieved by reloading the jumper at the top left of the panel. Each output has a jumper and 3 spikes on top of each other. If the jumper is on the lower two pins, the output will work automatically. If the jumper is moved to the top two pins, the output will continue to operate until the controller is turned off or the jumper is put back on the bottom two pins. If the jumper is removed, the output will not operate. Use only during commissioning, for example for venting purposes.
For installation, wiring, and modification of the parameters, it is advisable to use the replace cover open.
The controls are made in English (or other languages on request). The parameters are set using the universal controller in the same way.
On request, the online modul gives you remote access.
The controller comes with two temperature sensors with a 6 meter cable.
Outer diameter: 9 mm
Sensor cable length: 6 m
Maximum temperature: 125 ° C.
