EXTERNAL TEMPERATURE OFFSET FUNCTION
This function allows user to change the selected set point according to the external temperature as
measured by a (duly programmed) K30 transmitter and re-transmitted in digital format (TTL)
to TLK94 controller.
This function relies on 2 parameters, Ad1 and Ad2, to define the extent of the offset at operation
range limits, i.e.:
Ad1 is the value to be added to selected set point when external temperature gets below zero.
Ad2 is the value to be added to selected set point when external temperature gets above zero.
Example
SP = 70 (with external temperature = 0 °C)
Ad1 = +10
Ad2 = -10
If external temperature is +20 °C (limit set for the transmitter) the boiler set point changes as follows:
[SP + (Ad2)] = [70 + (-10)] = 60 °C
If external temperature is -20 °C (limit set for the transmitter) the boiler set point changes as follows:
[SP + (Ad1)] = [70 + (10)] = 80 °C
NOTE:
1) The sum of set point + offset will be limited by SPLL and SPLH parameters
2) When transmitter detects a probe error or is not working or not present, TLK94 will use the local
set point.
