Actuator / controller for

electrothermal actuators

Code: EK-HE1-TP

KNX device for control of electrothermal actuators for

zone valves in heating and / or cooling systems. It has

to be used in KNX installations for control of homes and

buildings.

Description

The EK-HE1-TP actuator / controller is an ekinex

S-mode bus device for the control of electrothermal ac-

tuators and / or motors for zone valves installed on di-

stribution manifolds of installations with radiant panels or

radiators. The 8 output channels use TRIAC to ensure a

noiseless command and a high number of cycles. The de-

vice may work in combination with NC (normally closed)

or NO (normallly opened) actuators and may be used in

installations with 2 or 4-pipe hydraulic distribution; in the

latter application it is possible to interlock the outputs,

completely closing the active valve before the opening of

the coupled valve, avoiding the mix of heating and col-

ling conveying fluids. The device is provided with a mem-

brane keypad for manual control of the outputs and LED

indicators for the diagnosis of the operation state and of

alarms triggered by short-circuit of the outputs or power

failure. The device can be configured as simple actuator,

in combination with one or more KNX room temperature

controllers, or as actuator / controller with acquisition of

max 2 temperature values from KNX room temperature

sensors. 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 or 24 Vac power supply for

the electrothermal actuators.

Functional characteristics

• 8 configurable channels for use with NC (normally

closed) or NO (normallly opened) electrothermal

actuators

• Independent configuration of each output channel

as actuator or actuator / controller for 2 or 4-pipe

systems, channel in parallel or as simple controlled

output through communication object

Datasheet STEKHE1TP_EN

KNX

• Detection and reporting of short-circuit through moni-

toring of the current absorbed by the electrothermal

actuators connected to the outputs

• Detection and reporting of lack of supply voltage on

the electrothermal actuators connected to the outputs

(only if supplied at 230 Vac)

• Selective single channel enabling for only one con-

duction mode. In systems with radiant floor panels, the

function allows to simulate different steps of laying of

the pipes depending on the conduction mode in order

to achieve a higher cooling power

• Valve protection function (anti-seizure) during long

periods of inactivity

• Delayed activation of the outputs (in the range 5-40

s) in order to avoid power-absorption peaks by the

electrothermal actuators

• Automatic evaluation of the energy demand, available

as a communication object, to activate the thermal

generators and / or a circulator

• 4-channel and 4 inputs each channel logic functions,

to realize combinatorial building automation logic

through AND, OR, NOT and exclusive OR blocks

Other characteristics

• Housing in plastic material

• Mounting on 35 mm rail (according to EN 60715)

• Protection degree IP20 (installed device)

• Overvoltage class III (according to EN 60664-1)

• Classification climatic 3K5 and mechanical 3M2 (accor-

ding to EN 50491-2)

• Pollution degree 2 (according to IEC 60664-1)

• 4 modular units (1 unit = 18 mm)

• Weight 160 g

• Dimensions 72 x 90 x 70 mm (WxHxD)

Use

The device may be used as simple actuator or as actua-

tor / controller.

Actuator

The device receives controls and parameters via bus by

one or more KNX room temperature controllers.

• 8 or 4 ON / OFF or PWM independent outputs respec-

tively for 2-pipe or 4-pipe installations

• Heating / cooling changeover from bus

Actuator / controller

The device receives the temperature value via bus by one

or more KNX temperature sensors.

• 8 independent regulators (2-pipe systems) or 4 in-

dependent regulators (4-pipe systems), ON / OFF or

PWM

• Heating / cooling changeover from the bus (2 or 4-pipe

systems) or automatic switching based on the room

temperature (4-pipe systems)

• Management with single setpoint or absolute or rela-

tive setpoint with that may be activated through the

HVAC system mode

• Acquisition of two room temperature values received

via bus from other KNX devices with calculation of a

weighted average

• Surface temperature limiting function through value

received from the bus for heating applications with

radiant panels

• Anti-condensation protection function through sensor

status received from the bus for cooling applications

with radiant panels

• Energy saving functions with limitations and / or exten-

sion of comfort mode, with status received via bus from

window contacts or presence sensors
