Integrated controller with two control valves and diff. pressure controller (PN 16)
IHPMM-F – flow mounting, fixed differential pressure setting
Description
IHPMM-F is an integrated controller which
consist of two control valves and one self-acting
differential pressure controller. It is developed
primarily for use in district heating systems. The
differential pressure controller closes on rising
differential pressure.
Two control valves are developed to control
heating circuit (HE) and domestic hot water
(DHW) production.
There are other possibilities to use controllers as
well:
- to use both control valves for heating
- to use both control valves for domestic hot
water production
In combination with Danfoss electrical actuators
AMV(E) can be controlled by ECL electronic
controllers.
Innovative compact design enables space
saving due to reduction of number components
and simple, fast and reliable mounting into
substation.
Control valves are used together with Danfoss
electrical actuators:
- AMV(E) 150
- AMV(E) 10 / AMV(E) 20 / AMV(E) 30
- AMV(E) 13 / AMV(E) 23 / AMV(E) 33 with spring
return function
- AMV 20SL / AMV 23SL / AMV 30SL with stroke

Installation positions
FOR INTERNAL USE ONLY
Up to medium temperature of 100 °C the
controllers can be installed in any position,
except with (connection neck for) electrical
actuator oriented downwards.

Note!
Installation positions for electrical actuator
AMV(E) have to be observed as well. Please see
relevant Data Sheet.
For higher temperatures the controllers can
be installed with differential pressure actuator
oriented downwards or horizontal, except with
(connection neck for) electrical actuator oriented
downwards.

Function
FOR INTERNAL USE ONLY
4 VD.LR.C 3.02 © Danfoss 06/2010 DH-SMT/SI
Temperature control
Medium temperatures on heating and domestic
hot water secondary sides are being controlled
by electronic controller (wheather compensator).
Electronic controller based on it’s algorithm
adequately, via electrical actuators, opens or
closes both valves.
Differential pressure control
Pressure changes from the flow and return
pipeline are being transferred through the
impulse tube and control drain in the actuator
stem to the actuator chambers and act on
control diaphragm. Control valve closes on
rising differential pressure and opens on falling
differential pressure to maintain constant
differential pressure.
