Hi,
recently changed valve & head (head burnt out). Wired up as instructed, completed all checks and confirm working as expected. I have noticed that a 'feature' that is probably there all the time, but only apparent when you start looking.
If you have HW Tank stat satisfied, the controller set to CH ON + HW OFF, and then the controller/timer switches CH OFF, the V4073 is left in 'hold in last position' mode as it is getting a live on the Orange and Grey wires. This means the valve is powered on (and gently vibrating) for long periods. The only way to stop is is to flick the HW ON for a bit to reset valve - you hear the spring pull the valve back. It is doing what the guide states, but I am surprised in this energy efficient age we have all these valve consuming power in a mode that they must be in for the majority of the time. Any explanations, thoughts, opinions or workarounds or I am just a sad git?
