Hi,

I have mapped the temperature sensor of an SCS8 to an entry in the control menu, but it always reports in Fahrenheit. I would like to have the announcement in Celsius. In the SCSman.pdf it says:

The temperature may also be announced in either ̊F or ̊C. The default setting is in ̊C. To change the settings to ̊F, the total value of location 39 (as shown in the “Comfort II Ultra Program Worksheet (FS34)”) must add an additional value of 1. This is to be done via the Location Menu in the Engineer Menu on the keypad.
Note: Changing the value of location 39 only changes the announcement made by the keypads and does not change the value of the registers.


However, I found this in the firmware section:

Version 2.004 – 22 June 2010

Support temperature sensor report in Celsius. Take note that the temperature unit now is 0 for Fahrenheit and 1 for Celsius, which are the reverse from previously.


My version is 2.004. The current value of location 0039 is 168, but it makes no difference when I change it to 169 and reset. Please advise how to change to ºC.
Thanks

The SCS is only able to report its temperature in degrees F
The location 39 bit is only for annnouncement of Degrees C or F, it does not do any conversion
There is an action to convert degrees F to C, egGet Counter 001Convert degrees F to CSet Counter 001

Sorry, I made a mistakeThe SCS can in fact report the temperature in C or F
But you need to reset Comfort after changing Location 39

Thanks, but as I said in my original post, there is no difference after changing location 39 to 169 (from 168) and resetting Comfort. I still hear the value stored in the sensor (at the moment "66").

We have discovered the cause of the problem and should be fixing it in the next  firmware release

Hi,

Has his been fixed yet ? 
I am trying to use the thermostats function, and am finding that my scs's re reporting in farrenheight no matter what setting I change in comfigurators miscelaneous settings menu!The thermostat function will not allow setting of temperatures in the farrenheit range, only seems to accept celcius range (15 to 32 max for example)
I also tried to change through engineering menu location 39, but no cange also even after sytem reset.

There is a workaround to the temperature units reported from SCS


Get Sensor Register 6
Convert to C     (This converts the temperature to Celcius)
Save Sensor Register 6

Hi slychiu, does this actually change the sensor value to degrees c, or does it Just create Angelis for you to store in a counter as degreesbc ?[size=
]The reason I ask is that the temperature function only works based on sensor value and not a counter value ?

I left out save to sensor, which I have corrected above
After conversion to Celcius, you save back to the same sensor

Hi,

I have created the above response to convert the sensor register value from 'f to 'c.  Where should I call it from?  How often should I call it? 

I am reporting the temperature in the control menu and want to make sure that I am always going to see it in 'c.  I am concerned that if the temperature changes, it will then be in 'f and if I then look at the temperature in the control menu it will not yet have converted to 'c.

 

Thanks,

Clinton.

Cool.  Thanks.

Does that not cause an infinite loop?  Temp changes -> response changes temp -> temp changes -. response...

It does not, because the sensor response is activated by an external message and not by a Response
