How to set the Salus receiver to work with the regulator - auto or manual?

Hello, could someone explain to me how the receiver should be set to cooperate with the regulator? Car or manual? How is it different?

AUTO - switches the room controller
MANUAL - Enabled regardless of the status of the room controller

So it must be on the car and I want to control the heating via the controller?

Whether it is auto or manual, it will always work in accordance with the regulator, only with the difference described in #2.
The rest of the details are in the manual, its.

I have it set like this



When switching to auto mode, the boiler runs without a pump, so it doesn`t work as it should? I wonder if I have something wrong because the temperature shown on the controller screen does not match the one I set the controller to. Cool radiators, not cold, still don`t go down to 21C, and I have the economy one at 7pm.

that is, bad.
The MANUAL setting means that the circuit is permanently closed, just like if you had a permanently closed jumper on the boiler and the receiver does not respond to signals from the room regulator (transmitter).
Only the AUTO setting causes the receiver to respond to signals from the transmitter.
If you prefer MANUAL mode, why did you buy the controller? What you have set up makes no sense.

In AUTO mode, if the transmitter, i.e. the room regulator, gives a heating signal, the green diode on the receiver will light up, the circuit will be closed and the boiler will turn on the heating.
If the transmitter gives the HEATING STOP signal, the green diode on the receiver will turn off, the circuit will be opened and the boiler will turn off the heating.
The operation of the pump after the burner is turned off depends on the so-called settings. pump overrun in the boiler settings.
When a specialist connected this Salus to you, the specialist should have set it up on the boiler or told you what to set it up and how, and if you did it yourself, now you have to set everything up yourself.

Maybe the changeover contact in the receiver is connected the other way around and instead of providing a "jumper", it "opens" and the boiler does not turn on and vice versa.

This qualifies for proper reconnection by a specialist, according to the instructions, also mentioned in #6, 7.

I have RT510RF and in the receiver I have COM and NO connectors, so I do not have the NC option to connect the receiver incorrectly.
I also ruled out incorrect connection of the receiver, because there is nothing to damage there

Well, it`s as simple as pie, but if you want to have a pump and a solo boiler, you need to connect a relay and a coil for 230 V/AC.

If you have a gas boiler, the pump is built into the boiler, so the regulator turns on the boiler and the built-in pump automatically, so an additional relay is unnecessary and I installed this variant.
The question was how the receiver should be set to AUTO or MANUAL, the answer is AUTO.
For people who know the basics of the subject, this connection is simple, and if someone has no idea about it, they should not attempt it at all.

The author has drawn it in two versions so as not to split it up, also for other interested parties.
The answer is always auto (OFF/ON with the Salus regulator), the control applies to the upper diagram (to be precise).
This is the position of the receiver switches:
1. HE
2. AUTO

I`ll join in on the topic. I have a floor installation with several circuits that are turned on/off with Salusa T30NO actuators. The actuators are controlled by a set of 091FLRFV2 wireless regulators with an RXRT510 receiver.
As this year I launched a heat pump with new underfloor heating circuits, I would like to test the underfloor heating without cutting off the circuits. I thought that the force T30NO - Normally Open - after disconnecting the RXRT510 from the power supply, would leave the circuits open, and this NO probably means that they extend, thus closing the underfloor circuits... And they close and close the circuits. Do you have any idea how to keep the actuators in such a position without unscrewing the actuators and without changing the programs in the controllers so that they do not close the underfloor heating loop?

I don`t know what you have, but I quote the description from the manufacturer`s website:

Quote:

NO type actuators are normally open devices, which means that when there is no current, the actuator is in the open position. The status of the actuator can be quickly checked thanks to the indicator element.

this is the description from the Salus website regarding the T30NO_24V_M30x1_5 actuator.

Set the room controller to cooling mode (page 21). The contactor in the receiver will work as NC.
This means that when the temperature rises above the set value, the controller will start closing the actuator. Below will be opening.

@Nargo
it wasn`t about that, but about the fact that the valve is supposedly NO, so with the receiver turned off, @boruurob expected that the heating would work normally, but it doesn`t.
Either it has an NC valve instead of NO, or maybe the room regulator is in cooling mode instead of heating mode.
But @boruurob hasn`t written anything since December 19, so we can guess what happened to him.

Question: I have a heat substation and I have installed a Salus RT520RF controller with a RXRT 520 receiver and it has broken down, you can't buy it separately but you can buy the 510 receiver separately (I won't be using the 2 extra A and B contacts to connect the opentherm to the substation unfortunately they are not suitable) and my question is whether the rt520rf will work with the 510 receiver and whether I will lose anything else apart from the A and B contacts, Jacek
