Siemens Universal controllers RMU710B, RMU720B, RMU730B CE1P3150en
Building Technologies Appendix 03.10.2011
 General limiter acts on all sequences
 Sequence limiter, can be set as min or max limiter, acts on a
adjustable sequence (closing)
 Universal shift
 Sequence locking acc to OT
 Fault message for unacceptable control deviation can be
activated

Controller 1 (Flow temperature)
Controller 1 basic type C:
 Universal shift ( )
 General limiter (gen. limiter)
 Sequence limiter (seq. limiter)
 Sequence S1…S5 load (y)
 Sequence S1…S5 pump (p)
Activate sequence controller dependent on demand, settable as P,
PI or PID controller, for demand-dependent flow temperature control
(chilled water or 2-pipe systems H/C) flow temperature sensor readily
wired to N.X1).
 Configurable sequence assignments; one load output (modulating
output A…D, step switch 1…5) and a pump can be connected to
each sequence
 Heating sequences S1, S2 and S3 (\\\_)
 Cooling sequences S4 and S5 (_//)

 Differential input (diff)
 Universal shift ( )
 General limiter (gen. limiter)
 Sequence limiter (seq. limiter)
 Sequence S1…S5 load (y)
 Sequence S1…S5 pump (p)
Universal sequence controller, as P, PI or PID controller.

Configuration Functions
a
IAQ controller
 Input  Room air quality control
 Open outside air damper
 Switch on fans at poor air quality (Precomfort, Economy)
 Changeover of fan speeds (with 2-speed fans)
 Increase fan speed (speed-controlled fans without pressure
control)
