Hi All
I'm looking for a circuit to do the below:-
When a switch is turned on (Afterhours Switch) When the temp reaches 33C a relay closes and when the temp reaches 25C the relay turns off.
I thought this wouldn't be to hard to do, so I got 2x thermostats. 1x to set at LOW Temp point and 1x to set at the HIGH Temp point, I made the assumpution that the LOW setpoint's built in relay would be closed after hitting 25C and above opps fail I forgot the 1.0C threshold setting.
So this is what I want.
Upto 33C Relay=open
AT 33C Relay=closed
Down to 25C Relay=closed
At 25C Relay=open
Help please, having some trouble remembering 30yrs ago of theory.
Thanks
