Controller for mixing group
Code: EK-HH1-TP
meric display and membrane keyboard
• Change of a subset of regulation parameters through
alphanumeric display and membrane keyboard
KNX device operating as a controller for mixing group.
Impiego in impianti di automazione di case ed edici a
standard KNX.
Description
ekinex®EK-HH1-TP allows to control a mixing group for
conveying uid in heating and/or cooling applications for
building. The device controls the opening / closing of a
servomotor for mixing valve and starts / stops the circu-
lating pump of the hydraulic circuit. The device allows the
acquisition of the delivery and return temperatures of the
conveying uid and the external air temperature, depen-
ding on the choosen regulation mode. It can be used
a 3-point oating servomotor points or one with 0...10V
input signal. The seasonal changeover (heating / cooling)
may happen from the bus, through a binary input (con-
gured for the purpose) or manually on the membrane
keyboard. The device integrates a KNX bus communica-
tion module and is realized for mounting on a standard
35 mm rail. The device is supplied by the KNX bus and
requires an additional 230 Vac power supply to operate.
Functional characteristics
• Control of a servomotor for mixing valve (3-point oa-
ting actuator or actuator with 0...10 V control signal)
• Start / stop of a circulating pump
• Regulation mode can be set separately for heating
and cooling
• 2 relay outputs for switching / controlling addtional
functions
• 3 inputs for passive temperature sensors (NTC 10 kΩ
at 25°C) for acquisition of conveying uid delivery and
• return temperatures and external air temperature
• 2 congurable inputs as analogic for passive tempera-
ture sensor (NTC sensor 10 kΩ at 25°C) or digital (e.g.
for condensation sensor or ow request contact)
• Connection of 230 Vac or 24 Vac external power sup-
ply for 3 point oating servomotor
• Two logical functions with 16 objects each
• Overtemperature (heating) and undertemperature
(cooling) alarm management
• Condensation sensor alarm management
• Monitoring of operating parameters through alphanu-

minal block included in delivery and inserted into the slot
at the left bottom of the housing.
Characteristics of the KNX terminal block
• spring clamping of conductors
• 4 seats for conductors for each polarity
• terminal suitable for KNX bus cable with single-wire
conductors and diameter between 0.6 and 0.8 mm
• recommended wire stripping approx. 5 mm

Mounting
The device has degree of protection IP20, and is there-
fore suitable for use in dry interior rooms. The housing
is made for rail mounting according to EN 60715 in bo-
ards or cabinets for electrical distribution. The correct
mounting is when the KNX bus terminal is located at the
bottom. When installing be sure to leave accessible only
the front panel; all other sides must not be accessible. For
the mounting proceed as follows:
• with the aid of a tool bring the locking device in the
fully lowered position (a);
• place the upper edge of the rear inner prole on the
upper edge of the rail (b);
• rotate the device towards the rail (c);
• push the locking device upward until it stops (d).

Warning! In order to supply the KNX bus lines use
only a KNX bus power supply (e.g. ekinex EK-AB1-
TP or EK-AG1-TP). The use of other power supplies
can compromise the communication and damage
the devices connected to the bus.
!
Warning! When the device is installed in the boiler
room, make sure it is accessible only the membra-
ne keyboard and that the connections are properly
protected against the ingress of dust or liquids.
