Help with heating thermostat rule

Hi everyone.
I’m trying to get a diy esp8266 ds18b20 thermostat for my heating working. I want it to come on and off depending on desired temperature. I’m pretty close but I can’t seem to work out where I’m going wrong.
In my log I can see the temperature change so the sensor is working. Also my wanted temperature is showing in log and I can switch it manually via basic ui. But whenever I try to change the setpoint the really doesn’t go on or off. I have attached some screenshots of logs and stuff.
Hope someone can help.
