Do you have a question about the 103 and is the answer not in the manual?
Questions and answers
Can you use a 103 to replace a 102 on a heating system that has a thermostat in the boiler and water and heating works together and can't work separately
Yes, a Danfoss 103 can replace a Danfoss 102 in a heating system with a combined thermostat for water and heating, but with differences in functionality. The Danfoss 102 has selector options for Water only/Off/Water and Heating, while the 103 acts as a single on/off timeswitch controlling both boiler and pump together. If the system wiring and wallplate are compatible, the 103 will work but may not offer separate control for hot water and heating.
