Self-acting controllers integrated to heat exchanger (PN16)
IHPT, Termix TPV – Flow-compensated temp. controller with ∆p controller built in (NO)
Description
IHPT
Self-acting controllers are designed to be
integrated directly to heat exchanger. They are
developed to control instantaneous heating of
domestic hot water by means of heat exchanger.
The family of products offer full flexibility
of different requirements regarding control
performance and idle condition (no load
conditions).
Innovative design enables simple, fast and
reliable connection to heat exchanger and most
important production of ultra compact and user
friendly stations for heating of domestic hot
water.
The controller is connected to primary heating
system as well as cold water system. To avoid
risk of leaking from one media to the other the
controller is equipped with double sealing.
Between both sealings there is a bore to the
outside of the valve. In case of leakage from one
sealing the media can escape through the bore.
There are two different controller housings:
- original (IHPT)
- Gemina housing (Termix TPV)
Termix TPV controller has the same function as
IHPT controller, but different (Gemina) housing.
Controllers have:
- WRAS approval,
- ETA VA approval.
Main data:
• DN 15
• kVS 2,4; 3,0 m3/h
• PN 16
• Setting range: 45 ... 65 °C
• Temperature:
Circulation water 2 ... 120 °C
• Connections:
- Union nut
- External thread
The capacity of controllers fully covers the needs
of domestic hot water for flats, one family houses
or dwellings and can be mounted to district
heating network directly, to a block of heating
systems or central located boiler system in a
dwelling house.

Sensor installation Temperature controller
Controller must be mounted on cold side of heat
exchanger (district heating outlet and domestic
cold water inlet side).
IHPT, Termix TPV controllers are delivered with
standard sensor.
Standard sensor
The sensor must always be placed warmer than
the controller.
Temperature sensor
Can be mounted on any direction.
For best performance it is recommended to
install the sensor facing up.
Strainers installation IIt is strongly recommended to install strainers
on both the cold water pipeline and the district
heating supply line.
Sizing
Example
Instantaneous domestic hot water production
requires primary flow of 800 l/h. Minimum
system differential pressure is 0,8 bar.

Function The controller has three main functions that
can be mounted in the controller based on
application demands:
QC Proportional flow controller
TC Thermostatic controller
DP Differential pressure controller
TC
QC
DP
To minimise the risk of calcium deposits on cold
water side and sensitivity to high temperatures
the controller is mounted on cold side of heat
exchanger (district heating outlet and domestic
cold water inlet side). In standard applications
at standard conditions with Danfoss heat
exchanger XB 06 primary return temperature is
below 30 °C.

Function (continuous)
Flow-compensated temperature controller with integrated differential pressure controller
(IHPT, Termix TPV)
Flow-compensated temperature controller IHPT with integrated differential pressure controller
When tapping starts, cold water flows into
secondary side of controller ① passes the
secondary side cone (QC) ②, leaves the
controller ③ and enters the heat exchanger.
When no load (no flow on secondary side) the
controller maintains constant temperature in
the heat exchanger few degrees below adjusted
temperature (Idle temperature).
The pressure drop generated on the orifice is
transferred to the diaphragm ④ which transfers
the force to the spring ⑫. This results in moving
of the main spindle ⑤ to the right which opens
the primary side cone ⑥.
The differential pressure controller ⑧ controls
the pressure over control valve and therefore
enables 100 % authority of the controller in all
conditions.
The opening results in primary flow entering
into controller ⑦, passing integrated differential
pressure controller (DP) ⑧, primary side cone
(TC) ⑥ and leaving controller ⑨.
The temperature sensor ⑩, mounted to
the secondary hot water side is sensing the
temperature. If the temperature is deviating from
setting temperature the thermostatic element ⑬
will move (open/close) primary side cone ⑥ until
desired temperature is reached.
Not to influence on tapping flow from
thermostatic adjustments the spring ⑫ is
mounted between main spindle ⑤ and
diaphragm which can be compressed when
needed.
Settings Temperature setting
Temperature setting is adjusted with handle for
temperature setting.
By rotating the handle for temperature setting ⑬
the temperature of tapping flow can be adjusted.
Domestic hot water circulation ⑪ are placed
directly on the controller and therefore minimize
the costs for mounting and optimize space for
the piping.
IHPT, Termix TPV controller
By turning it in (+) direction the setting is
increased, by turning it in (−) direction the
setting is decreased.
Scale on handle is approximate indication of
temperature setting where MIN represents
minimum and MAX maximum value of the
thermostat temperature setting range.
Temperature setting between MIN and MAX
values changes approximately linearly.

Mounting specifics Connections to heat exchanger
Union nut connection
Second option is with union nuts to standard
threaded heat exchanger connections (fig.1)
which have distance between them 45 mm.
In order to cover the tolerances of heat
exchanger production special union nuts were
developed which can tolerate dimensions of
45 ± 1,5 mm (Factory assembled).
In this case standard fittings should be used
on hot side of heat exchanger.
Connections to pipes
For connecting controller to station ¾”
connections are used.
