Pumps for All Occasions 2.0

Need to hook up a water circular pump to 2 furnaces. What do I need to do to hook them up?

I have a taco circular pump that has terminals for a red and white wire from my furnace / thermostat., it will turn the pump on and off as the thermostat calls for heat. I tested it and it works well with 1 furnace. I have 2 furnaces / thermostats that I would like to hook to the one pump so the pump will only come on when either furnace calls for heat. I am thinking I may need another part to do this. Not sure if I can tie all the wires together from the 2 furnaces into the pump without having an issue or having both furnaces running at the same time any time one furnace calls for heat. Does anyone know what part I need and where I can purchase this part if I need one so that the pump will start when either furnace calls for heat?

Your best bet would be to get a second pump. Connect one to each furnace. This way they are totally independent of each other and can run when necessary.
