Running version 4.2.4 on my Gateway against a Remeha Avanta I dynamically change the Max CH water setpoint using the SH command (to force HR80 to fully open in at least one zone but that is another subject).

I noticed the PS=1 command never returns the Mac CH setpoint I have set. Looking at the message log I see, after issuing SH=58:

Code: Select all

T90393C00  Write-Data  Max CH water setpoint: 60.00
R90393A00  Write-Data  Max CH water setpoint: 58.00
B50393A00  Write-Ack   Max CH water setpoint: 58.00
A50393C00  Write-Ack   Max CH water setpoint: 60.00

The gateway actively caps the value to 58 and the boiler responds accordingly. But when I send the PS=1 command I get:

Code: Select all

10:29:47.095117  00000010/00000000,10.00,00000011/00000011,100.00,0/0,20.00,0.00,0.00,20.00,53.71,0.00,0.00,47.10,60/40,61/20,60.00,60.00,31072,18680,21024,22160,5672,16912,46232,0

Max CH: 60.00? What goes wrong here?

The only thing that's wrong is your expectation. The gateway uses a very simple rule for which data to store: It takes values it receives in Write-Data (data provided by the thermostat) and Read-Ack (data provided by the boiler) messages. That's usually the right thing to do. It is not able to read your mind and figure out that in this specific case you want something unusual.

So the Max CH water set point of the PS=1 command reflects the value the thermostat has requested/written. Not the actual setting of the boiler nor the override value set using SH=58. Which the gateway has stored successfully as we can see it override the thermostat request with R90393A00 and the boiler's answer B50393A00.

Is there a way to read the override temperature set by SH from the gateway?
