Issue
Is it possible to configure a Xenta 121/122 controller with an STR-150 and lock the thermostat so that the user cannot change the temperature setpoint from the STR-150 device?
Product Line
TAC Vista
Environment
- STR-150
- Xenta 121
- Xenta 122
- STR Sensor
Cause
In some applications, you do not want anyone to change the setpoint from the room unit.
Resolution
It is possible to configure the STR150 device so that it is not possible to adjust the actual setpoint.
- Enter configuration mode for the STR150 by Pushing the fan and bypass buttons simultaneously for 2 seconds to enter P0.
- In P0, hold down the bypass button and push the fan button three times.
- Press the fan button until you see P7, and change the P7 value to zero.
- To Exit Configuration Mode, push the fan and man button for 2 seconds. The timeout will exit configuration mode if idle.
