Hi,
I keep scorpions and would like to simulate natural conditions in their enclosures. My scorpions come from an environment with a large day night temperature differential. Currently I have a commercial controller that drives one ceramic heater at a constant temperature of 30°C.
My wish is to have a different day and night temperature. To this end I have found two circuits on the net. The first is day night controller and the second a heater controller. I am hoping to merge the two;
In the heater control circuit the temperature is set via a potentiometer. I would like to insert another potentiometer in the existing control circuit making one for the day and one for night. The potentiometer brought into the circuits will be determined by the relay output from the day / night circuit.
I have included the schematic of the original circuit along with the schematic including the addition pot and the relay from the other circuit.
Could someone confirm that the addition of the pot will not alter the circuit functioning.
I did note that the LV ground and the HV ground are tied together, is this OK?
