My radiant heat circulating pump runs without a call for heat. I did drop a thermostat when moving it, and the wires got disconnected. I began to re-attach them, without shutting the power off. I know, a mistake. I may have touched two live wires. Now the pump runs constantly without a call for heat from any of the 4 zones. Did I short something out? If so, how can I tell what I did? The fuse in the control box is still good, but is it possibly the transformer I damaged?
