Hi all, I am trying to set up a thermostat to control a small 240V heater (no more than 60W) that will heat a plant growing cabinet, to maintain a temperature of at least about 18C (exact temperature isn't critical).
I have a Velleman MK138 thermostat kit, but the relay power rating is only 24VDC, so I'm thinking I will use a mains (240V) relay, say this one.
My question is will I have to use the mains relay in addition to the Velleman kit, or can I replace the relay in the Velleman kit with the mains relay? If I could just replace the relay, it would be neater as it may all fit on the same board.
