I am running a hot water blower in my garage. Its a Modine HC-63 with a 1/12th hp motor. I am using a Johnson controls A19DAC-1C aquastat on the water pipe to control the fan but I want to control it with my ecobee instead. I havent done much research yet, but am looking for ideas on what type of relay to use. I should be able to send a 24v ac signal to turn it on.

My reasoning is that it will work like a forced air heating system for this one zone. Thanks in advance.

I got this worked out so I figured Id share in case anyone wants to do something similar. I used a time delay relay from Functional Devices. RIBD2421C.

It was very simple to wire up and it works great. Now I can control the fan independently from the heat using the thermostat and since its not a thermostatic switch there aren't any more issues of it blowing cool air in the heat mode when the zone shuts down.
