Welcome! Here are some tips for using this forum.
I have a new Bosch Greenstar FS with a FW 200 controller. I have an issue that when my thermostat calls for heat, it doesn’t turn on the pump or boiler. I used a multimeter and I have 22 volts across the lines. I noticed even when the thermostat inside the house is turned off, the pump still runs like there is a call for heat. Is there a programing issue with it or something else going on?
