Notes
- System 4-B is registered
automatically when sensor S2 is
connected. The necessary settings
become visible in the display
(registered when the unit is switched
on).
- Load-dependent compensation is
possible by connecting sensor S6.
Two independent compensation
curves can be set. Curves must be
set in P6.2 and P6.3 in P7.2 and P7.3
respectively.
- With reduced temperature, total stop
function in P1.2 has the following
influence:
0
Control according to reduced
setpoint (P9.0). Pump constantly
cut in.

Valve closes and pump stops
until room temperature falls to the
required temperature. Valve then
opens and pump starts until room
temperature has risen 1 degree.
- Relay status for different operating
