Good Eve Gentlemen,
We had this cold room which was converted to hot room before I joined this work. Everthing was fine until a month ago, they noticed the temp is higher than the set value, and alarm went off.
I couldn't find the schematics for this but I see there is a thermocouple connected to Ranco Digital temp controller (which I assume was for cold room before, the setting is set at C), and there is Watlow Series 998 which is supposed to turn heater ON and OFF based on temp set.The temp set is 44C but reaches 47C after some time. Watlow should Off the heater when it reaches Temp 44 right?
Please suggest, what am I missing here?
