OONO F-1057 Switching Electric Heating Relay
IMPORTANT!
⯈THIS MODULE OPERATES ON A HAZARDOUS VOLTAGE!
⯈All wiring must comply with national and local electrical code
regulations.
⯈Installation should be carried out by an electrician.
⯈ Disconnect power supply before installing the relay to prevent electrical
shock.
Features
- 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.
- LED indicator for relay action. On a call for heat, the relay is immediately activated, there is no delay.
- 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.
- Packing list: 1x relay module, 1x NPT 1/2” Zinc alloy conduit locknut, 2x M3x50mm screws.
NOTE: Not recommended for fast-cycling modulated regulation. For fast- cycling heating equipment, you may muse use Solid State Relay.

SAFETY INSTRUCTIONS !!!
-
Do not attempt to disassemble the unit as it does not contain any parts that are to be serviced by the
user. (Tampering voids warranty) -
Do not touch unused terminals when the module is connected to the AC power.
-
Handle the module gently and carefully. Dropping it can damage the circuit board and case.
-
Never exceed the protection limit values indicated in the specifications.
-
As safety requirement vary, please check with your local authorities.
-
Disconnect the module from the AC power before connecting new devices.
-
Wipe the device with a dry and clean cloth. Do not use detergents or other liquids that may damage the housing.
-
Keep the device away from children.
-
Facilitate the operation of the device by familiarising yourself with its adjustments and indications.
-
CZH-LABS and Electronics-Salon modules are not suitable for use or as part of life support systems, or systems that might create hazardous situations of kind۔
