Mid point/Tolerance

The Mid point (inval1) and Tolerance (inval2) parameters determine the range for the Deadband (mid-range). These parameters are displayed only when Deadband (mid-range) is selected for the On event. Any [VALUE] between -9999 and +9999* can be assigned to these variables.

* When the provided value is between -999.9 and +999.9, one decimal digit can be added to the integer part. The decimal part is automatically truncated if the value is outside of this range.

The Mid point and Tolerance offer an alternative method to define the High-Low range, where:

  • Upper bound = Mid point + Tolerance
  • Lower bound = Mid point - Tolerance

HTTP

The device will accept HTTP requests at the following URLs related to:

  • Low input:

(POST) http://[IPv4]/var_set?param=inval1_[PROCESS ID]&val=[VALUE]
(GET) http://[IPv4]/var_request?param=inval1_[PROCESS ID]

  • High input:

(POST) http://[IPv4]/var_set?param=inval2_[PROCESS ID]&val=[VALUE]
(GET) http://[IPv4]/var_request?param=inval2_[PROCESS ID]

A combination of:

POST: http://192.168.1.255/var_set?param=inval1_15&val=22
POST: http://192.168.1.255/var_set?param=inval2_15&val=0.5

will set the thermostat deadband range of the Deadband (mid-range) on Process #15 to 21.5 - 22.5.

Learn more in HTTP API.

Variables inval1 and inval2 are shared with the Condition thresholds and the High/Low input.

MQTT

This parameter can also be accessed via MQTT using [PARAMETER] = inval1 and inval2. Learn more in MQTT API.

Following two messages:

Topic: johndoe5896/home/thermostat/sub/process_15/inval1
Payload: 22

Topic: johndoe5896/home/thermostat/sub/process_15/inval2
Payload: 0.5

will set the thermostat deadband range of the Deadband (mid-range) on Process #15 to 21.5 - 22.5.
