Finally, it will feed it with 24 volts, provide power to the thermostat, and when the thermostat calls for heating or cooling, provide everything with control power. It will open and close the relay according to its settings. Since the PEK isn. For 24-1-60: LLS sealed coil rating (24 vac) 18 va maximum. These transformers are suitable for mounting in both plastic and metal back boxes. For 240 volt operation the primaries go in series and you would tie 2&3 together and apply 240 volts AC to 1&4. Zone 1 has optional priority over zones 2 through 4 and can be used to provide heat to an indirect domestic hot water tank. They are called pad-mounted transformers, and they serve to turn high voltage electricity that’s carried underground into lower voltage electricity that can be carried into your home and used to power your electronics. Disconnects all ungrounded conductors in OFF position. Check voltage at VAL of Ignition Control. com/the-book This is how to wire a mutli-tap transformer, how transformers work, and what the colors mean when connecting.

The 40VA output can power up to five (5) spring retrun dampers or a control panel with up to four (4) dampers. To keep the transition to a newer thermostat to minimum hassle, just choose a new model that abides by roughly the same size and shape as the old one. If there is no voltage read at the output of the transformer as read by a voltmeter, and power is available on the input side, the transformer has failed.
