145 Changeover time, TP

Circuit Setting range Factory setting

I / II 0.0 ... 23.9 16.1 / 16.1

The changeover time determines the moment when the activated

pump stops and the deactivated pump starts.

Please note this special setting range. The ﬁgures

to the left of the decimal point represent the time

in hours and the ﬁgure to the right of the decimal

point represents the frequency in days.

Example:

16.1 the change will take place at 16:00 hours

each day

20.3 the change will take place at 20:00 hours

every third day

0.2 the change will take place at midnight every

second day

8.0 the change will take place at 08:00 hours

every tenth day.

The changeover time is automatically deactivated if one pump

has an alarm or if only one pump exists in the heating system.

146 Pressure stabilization time, TST

Circuit Setting range Factory setting

I / II 1 ... 99 sec. 15 / 15 sec.

The pressure stabilization time starts when a pump switches ON.

The pressure stabilization time has to elapse before the controller

can read the pressure control switch.

Choose the pressure stabilization time.

When the chosen pressure stabilization time is too short, the

active pump will stop immediately after the pressure stabilization

time has elapsed.

153 Changeover delay, TCH

Circuit Setting range Factory setting

I / II OFF / 1 ... 99 sec. 5 / 5 sec.

The changeover delay is the time from the ﬁrst pump stops until

delay has elapsed.

The changeover delay has to be chosen in systems with two

pumps.
