Notes:
- System 2-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.
1 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
situations with this system is as
follows:
