Flue gas temperature sensor
* Here, the free inputs are available
The inputs on the basic module are designated RMK770.Xn, those on the extension
modules RMZ...Xn. If 2 identical extension modules are used, they will be called
RMZ789(1) and RMZ789(2).
After the assignment, following appears: "Flue gas temperature sensor N.X4" (N= short
designation of basic module RMK770).
By assigning input terminal RMK770.X4, the flue gas temperature sensor is activated.
For other settings, refer to chapter 7 "Boiler temperature control".
Assignments made or preconfigured assignments can be removed again by using set-
ting --- (none).

Available for selection are the free terminal pairs (Q1/Q2, Q3/Q4, Q5/Q6) for the on and
off signal (refer to subsection 3.3.2 "Terminal assignment and properties of outputs").
Refer to subsection 3.3.4 "Maximum configuration".
