The answer is probably very simple but I can't work it out can anyone help please.
We have.
Randall 4033 programmer near the hot water tank.
It has a timer with red and blue adjustable pointers A,B,C,D
A and C starting when we want the programmer to turn stuff ON and B and D when we want stuff OFF
For both the heating and hot water it has a separate On and OFF switch.
We also have a Drayton thermostat in the front room.
Adjustable from "Frost" to 30 degrees C
There is a red dot between 15 and 25.
I have three questions please.
On the Drayton what is the significance of the red dot, e.g. does it just indicate this is an optimum setting?
Does the Drayton control the Randall when it is running both on a "Timed" setting and when it is switched manually to ON?
What effect do we have on the Randall when we switch from "Timed" to manually turning either the hot water or the heating ON and then OFF?
I have found we need to turn the timer at least twice to reset the automatic switches on the dial but I am not sure if manually turning the systems ON and OFF while the timer is running means we have to do the same reset when we revert back to the "Timed" option.
I hope this makes sense.
Thanks for looking,
Bern
