Question
barend121 13
Hi all,
Today installed the horstmann/secure thermostat HRT4-asr-zw together with the horstmann thermostat.
Inclusion in fibaro went smooth, connecting the boiler-switch and the thermostat went smooth. When turning the wheel to 30 degree, it switched green (on) and turning the wheel to 5 degree it turns off (red).
Connected wire 2 and 3 to the Nefit boiler and tested the situation.
The nefit reacts opposite to the output of the boiler switch. When the boiler switch is off (red) there is no resistant measured with the multimeter, when the boiler switch is on (green) I measure endless resistant with the multimeter.
The nefit acts the opposite, no resistant, boiler on, lot's of resistant boiler off.
Sound this familiar for someone? And did I make a mistake?
Help is appreciated!
