Relay test

The eight output relays can be individually energized. Depending on the type of plant,
the following codings apply:
Input Plants with a valve (plant types
1–x, 3–x, 4–x, and 6–x)
0 Normal operation
1 All contacts open
2 Heating circuit valve OPEN (Y1)
3 Heating circuit valve CLOSED (Y2)
4 Heating circuit pump / circulating
pump ON (M1)
5 Charging pump / diverting valve ON
(M3/Y3)
6 Circulating pump ON (M4)
7 Multifunctional relay energized (K6)
8 D.h.w. valve OPEN (Y7)
9 D.h.w. valve CLOSED (Y8)
There are 4 choices to terminate the relay test:
• Entry of 0 on the operating line
• Leaving the setting level by pressing button
• Leaving the setting level by pressing the Info button or any of the operating mode but-
tons
• Automatically after 30 minutes

Sensor test

The connected sensors can be checked on operating line 163. In addition, if available,
the current setpoints and limit values are displayed.
On the display, the current setpoints are identified by SET, the actual values by
ACTUAL (also refer to section "28 Handling")
The 9 temperatures can be called up by entering 0...8:
Input Display SET
0 No display
1 Setpoint of flow / boiler temperature.
With the plant types using a boiler, the
switch-off point is displayed. If there is
no demand for heat, the display shows
---
2 Setpoint of room temperature.
With the plant types with no heating
circuit, the display shows ---
3 Setpoint of room temperature.
With the plant types with no rooms,
the display shows ---
