Specification Brand : OONO BulletPoint1 : The F-1057 Electric Heating Relay is designed to control a AC 120V line voltage resistive load from a low voltage thermostat. The F-1057 relay has a built-in 24 V transformer and is compatible with 3-wire (R, C, W) thermostats as well as 2-wire (R, W) mechanical and battery-operated thermostats. BulletPoint2 : Replacement for any brand relay. Immediate relay activation provides improved temperature control and comfort. Easy to install, merely munted it on the side of existing junction box and attached the wires from the new thermostat. BulletPoint3 : LED indicator for relay action. On a call for heat, the relay is immediately activated, there is no delay. BulletPoint4 : Polycarbonate plastic enclosure, all wires lead out via 1/2” mounting nipple, it can be flexible mounting with your junction box / outlet box. Two screw mounting holes are convenient for you to fix it on the wall or wooden board. BulletPoint5 : Packing list: 1x relay module, 1x NPT 1/2” Zinc alloy conduit locknut, 2x M3x50mm screws. BulletPoint6 : NOTE: Not recommended for fast-cycling modulated regulation. For fast-cycling heating equipment, you may muse use Solid State Relay.
