2.Wiring diagram


Terminal 1 and 2: Normally open contact relay
Terminals 3 and 4: 220V power connection
Terminal 5 and 6: Short circuit after locking thermostat factory parameter settings, the user can not modify.
Terminal 7 and 8: Temperature sensor connection
Note: The "load" refers to the controlled heating or cooling equipment

3 Button Description:
1). RST: Press the RST key to switch on and off, press the RST key in the off state once the boot, the boot
State according to RST button for three seconds and hold off.
2). SET:
A: Press the SET key once to enter the temperature control settings, press "UP" or "DOWN" to adjust, press "UP" or "DOWN" button for three seconds does not
Quickly put into adjustment mode. Press the SET button again to exit setting mode.



4, fault tips:
1) When the sensor is disconnected, the display shows --- and close the heating wire
2) When the sensor detects the temperature lower than -50 degrees, the display shows the LLL
3) When the sensor detects a temperature above 110 degrees, the display shows HHH



5, Caution:
* Cooling, heat load must not exceed the output contact, or may cause machine damage and cause a fire.
Disaster.
* A variety of connection wires and terminals connected to pressure well, otherwise, will cause the machine reliability.
* Please separate power wiring, relays, sensors, otherwise it will damage the machine.

The WH7016M factory setting is cooling enabled as standard. Has anyone worked out how to change it to heating? I can't see any jumper swithces inside...

I haven't fired mine up yet, as I'm still building the box to contain it.

On the inside, I noticed that the pcb is labelled as WH7016C, but clearly, the 5A relay has been substituted with the bigger 30A relay.

[Blackaddler]

In answer to my own question, I've found some instructions for the WH7016C, which are a bit more explicit, and explains all...

I have one of these and use it for BIAB so prepares water for mashing.

Connect the mains to 3 and 4, brown to 3, blue to 4

Connect the live wire (brown) to 1 as well
Connect 2 and 4 (blue from the mains) to the boiler.

You can use 13Amp connection blocks to make life easier as it can be difficult get two wires in 3 and 4

Im trying to wire up a WH7016 temp controller and cant get my head around it does this diagrame match up with the way you have it?

any help appreciated. thanks

[Blackaddler]

Which WH7016 is it, specifically?

[Down2Die]

Sorry its wh7016m, 30 amp one 6000w. i want to use it for my hlt tank to control mash and sparge temps, with 2 x 1.5 kw kettle elements. I was hoping I could use one socket and plug both into a double adaptor?

Your diagram is the same as the 220v one in the above post, so you're OK.

thanks blackaddler Ill wire it up as per my diagram then. jonnyt post had me confused saying Connect 2 and 4 (blue from the mains) to the boiler.. lots of head scratching ....

Hmm, I don't get that either...

[Down2Die]

Thanks man working now...only using two core wire, no earth on mains and the heater switch...not sure what im going to house it in either...is this advisable then? and would you plug two 1.5kw elements into a single socket via a double adaptor?

[Blackaddler]

You should house your TC in some sort of box.

I wouldn't risk 3kW [about 13Amps] through a single socket.

Screwfix do some cheap sockets. See this earlier post.

[Down2Die]

hey thanks for the useful information. where will I wire in the extra socket for another element on that diagram then? will it be a case of three blues in port 3 and 2 browns coming off port 1?

thanks

[Blackaddler]

I think that you'll have trouble getting 3 wires into port 3, but otherwise, yes.

I would connect the blue wire to a suitably rated block connector, and from there, take one to port 4 [to save crossing with the brown wire], and the other two to the N terminal on your sockets.

The brown wire could also go via a block connector, and then to ports 2 and 3. Otherwise, just loop 2 to 3.

The brown wires from port 1 go to the L terminals on your sockets.

Here's a pic of my WH7016M, mounted in an old PC PSU, with a single socket. Hope it helps.

[Down2Die]

that's a great help!!!! Looks lovely man. have since got an old cd rom and will mount tomorrow same as your other one. could these controllers be used for a simple herms setup?

[Blackaddler]

I'm not sure about the requirements for a herms setup, but it's feasable, I'd have thought.
