Discuss New home... domestic hot water linked to central heating? in the Central Heating Systems area at ElectriciansForums.net

The manual says CH and HW are programmable separately.
I seem to recall having a problem with one of these programmers where half of the functions never came up on the menu.
Had to be replaced.
 
Hi - does the pump run only when CH is on? It looks like it may need to run to circulate water when either CH or HW is calling, perhaps?
