CH52 is flashing on the controller. Unit will not switch on.

To pair/sync a second remote switch to an existing Intertek 3177973 receiver, you will need to follow these steps:

1. Turn off the power to the existing fan/light unit by switching off the circuit breaker or removing the fuse.
2. Locate the "learn" button on the receiver. It is usually located on the back of the receiver or the control box.
3. Press and hold the "learn" button on the receiver until the LED light on the receiver starts flashing.
4. Press the "on" button on the new remote switch for about 5 seconds. The LED light on the new remote switch should start flashing.
5. Release the "on" button on the new remote switch. The LED light on the new remote switch should stop flashing, and the LED light on the receiver should stop flashing.
6. Test the new remote switch to make sure it is controlling the fan/light unit properly.

7. Turn on the power to the existing fan/light unit.
It's important to note that these steps are general guidelines, and the specific steps may vary depending on the model of your Intertek 3177973 remote control unit. Consult the manual for the specific steps and precautions before pairing or syncing on your remote control unit.

Press PAUSE/CANCEL twice to clear the display.

• If there is no water in the unit:
  1. Make sure that both valves at the water source(s) are turned on all the way.

Possible that the switch is defective, there is fault in the line to the control unit from the switch of the control unit is faulty.
check these one by one.

Possible failure of the flash unit or the trigger to the unit from the main controller unit of the camera. Since you are not able to switch on the flash manually the fault can be due to either of these sections , a possible electronic failure within the camera.
You will need some expertise to open and check for the power to the flash, if so the flash unit is faulty.
If not the controller unit is faulty..

Once you have installed the jumper, you will need to kill power to the furnace for about a minute to reset the board. Make sure the the jumper is making good contact. Sometimes they appear to be plugged in but still are not making contact.
