Service Functions
After the basic programming of Temperature Setpoints is complete, the programmer proceeds to
programming of the Service Functions, if desired.
The Service Functions are a continuous loop of programming steps (”functions”) which the pro-
grammer moves through by pressing the “Service” key. These steps are described in this section
of the chapter. The Service Functions loop and basic programming is diagrammed below.
There are three ways to exit the Service Functions loop:
1. Just wait (approx. 10 seconds) and the controller will automatically return to the actual temper-
atures display,
2. Press the Service key until you are back to the actual temperatures display, or
3. Press any Hose or Head key and you will return to the actual temperatures screen.
