“After 37 years in the heating profession, wiring relay after relay after relay is finished!! You run one power line in, loop to each circulator, hook up thermostats and boiler TT all in one place! Saves you time, money & your back. I use this on every multi-zone system.”
“I'm a homeowner with some electrical experience and I was able to wire and set up this control quickly and easily in my house. It's great to be able to see which zones are calling for heat.”
“Many newer condensing boilers that are using the downflow firetube stainless steel boiler designs now have a microprocessor control system that imposes a 4.8 DC voltage signal across the T-T terminals. Older systems that use a 24-volt signal could previously be used to operate two-wire digital power-stealing thermostats. With the new design boiler control this is not possible and the new boilers must be connected to either a dry contact thermostat for their T-T signal to fire or if using an electronic thermostat that must be powered, this TACO Pump control is essential as it will provide the 24-volt source necessary to operate newer digital thermostats and will also provide the dry contact relay closure for the boiler T-T signal that will now switch the 4.8 Volt DC voltage for the control's microprocessor to begin firing the boiler and operate its selected pumps via the boiler controls.”
“Great relay with easy install. Great to work with. I ordered the wrong model by mistake and they quickly got me the correct one and full credit on the return all at the lowest price. Will definitely use them again.”
“I am not a pro, but felt like one after I installed this unit. It was the finishing touch to my infloor heating upgrade. Thanks , especially when they wouldn't sell it to me locally "because I didn't have a license."”
