1. Product description
Secos is a highly innovative control system for surface temperature control where both volume flow and temperature are constantly
measured and optimally controlled. This ensures permanent hydraulic balancing at all times.
1Secos system manifolds
• Supply and return manifolds made of stainless steel 1" female
thread.
• One filling / emptying / flushing / venting device per manifold.
• Pre-assembled snap-on board to accommodate the Secos
actuator.
• Secos multi-sensors mounted and wired at the factory.
• Delivered ready for installation on manifold bracket with sound
insulation.
• Outlets in ¾" Eurocone.
• Including Simplex filling and drainage plugs.
2Secos energy saving controller
• Central core of the Secos Energy Control System.
• Evaluation of the system data and automatic control according
torequirements.
• To control the flow rate as well as the heat output in each circuit.
• Suitable for heating and cooling.
• Bus communication between energy-saving controller and
actuators.
• For up to 8 seperate room thermostats
• Assignment of the room thermostats to Secos actuators possible.
• With building management system connection (Modbus).
• Wireless connection via app Flamconnect.
• External condensation monitor can be connected.
• Valve and pump protection function.
• For all other features see "Functions & Features":
3Secos actuator for ceramic valves

5Secos multisensor
• For recording the volume flow and return temperature in each
heating circuit.
• No moving elements.
• Minimal pressure loss.
• Zero-flow detection.
• Prewired at the factory.
6Secos supply line temperature sensor
• Recording of the supply line temperature in the system.
• Additional safety device for monitoring the maximum permissible
supply line temperature.
7Secos disc valves
Unlike conventional standard systems with li valves, Secos works
with ceramic disc valves which are actuated by a rotary movement.
The specially designed ceramic discs allow linear valve opening,
which ensures a uniform valve characteristic curve. In conjunction
with the Secos actuators and the infinitely variable valve positions,
this enables very precise control of the volume flows in all heating
circuits.
• Disc valve with trend-setting ceramic technology.
• For heating / cooling applications.
• Wear-resistant.
• Long service life.
• Stepless and precise supply line control in combination
withSecos actuators.

2. Introduction
These instructions describe the installation, operation and maintenance of the Secos control system for surface temperature control.
Please read these instructions carefully before starting the installation work.
In the event of non-observance, all guarantee and warranty claims are void.
The instructions are intended for trained specialist tradesmen who have the appropriate knowledge in handling heating systems,
waterpipe installations and electrical installations.
Installation and commissioning may only be carried out by trained specialist personnel.
The illustrations are symbolic and may deviate from the actual product.
Subject to technical modifications and errors.
2.1. Intended purpose and proper use
The Secos Energy Control System is used to distribute heating water in water heating and cooling systems. The system simultaneously
records and controls the volume flows and temperatures of individual circuits.
The Secos Energy Control System is ideal for both new buildings and refurbishments.
The control system may only be operated with the media, operating and ambient conditions specified in the technical data.
The Secos Energy Control System may only be installed and operated in frost-protected, dry rooms.
The Secos Energy Control System should be protected against solar radiation, heat radiation and vibration.
Operation outside the permissible operating and ambient conditions can cause damage to the system.
Usage contrary to the regulations and changes in assembly, construction or components can endanger the safe operation of the system
and lead to the exclusion of all warranty and guarantee claims.
2.2. Flamconnect app for operation
Commissioning the energy control system.
XThe Flamconnect app must be installed on a terminal device (Android or IOS) before commissioning and operation.

6.3.1. Installation position
The Secos system manifold can be operated
in various installation positions.
However, if the system manifold is to
be operated outside the recommended
installation position, the energy saving
controller unit must not be placed in areas
where water ingress is a risk.
The hydraulics must be checked for
leak-tightness before installation of the
electronics.
It must be ensured that no moisture can
enter the electronics.

8.1. General note on connection
General
Work on the electrical system and the opening of electrical housings may only be carried out when the system is de-energised and only by
authorised specialist personnel. Ensure correct terminal assignment and polarity. Protect the electrical components against overvoltage.
Improper electrical connection may result in danger to life through electric shock.
XElectrical connection should only be carried out by an electrician approved by the local power supply company
and in accordance with the locally applicable regulations.
XDisconnect the supply voltage before working.
XDo not open the housing parts!
