Product details
Control unit, Hydraulics and control module for pressurisation, degassing, and water make-up in sealed heating water and cooling circuits.Constructed in compliance with DIN EN 12828 and the requirements of VDI 4708, with CE marking.Suitable for use in noise-sensitive areas.
Functional unit comprising a hydraulic part and a Control Touch operating unit. Both are ergonomically combined in an easy-to-maintain modular floor-standing framework system made of EV 1 anodized aluminium precision sections with CE marking.
Hydraulic section:
Pressure maintenance is achieved by a stainless steel centrifugal pump in conjunction with a robust, dirt-resistant motor ball valve, with a dirt trap acting as an overflow device. A safety valve is provided to protect the connected Variomat primary vessel VG or secondary vessel VF against overpressure. System pressure is measured by an electronic sensor. System connections on the discharge side are designed as secured shut-off ball valves. All fittings are mounted on a rotatable base plate to allow for a more flexible arrangement of the hydraulic system.
The Control Touch control unit with TFT colour display, including communication electronics, is integrated into a robust plastic housing designed as a panel and mounted Horizontally directly on the controller. An optional separate and Vertical wall mounting at a maximum distance of three metres from the power electronics is possible. Communication electronics comprising:
- 4.3" resistive colour touch display for programming, operating documentation and monitoring, as well as the provision of help texts for all functions
- two RS485 interfaces as data and communication interfaces
- a serial TTL interface with two connection terminals for connecting 2 I/O circuit boards
- a potential free output for transmitting the group message
- two galvanically isolated analogue outputs, e.g. for system pressure
- an input for analysis of contact water meters
- Slot for a compact bus module, one SD card, e.g. for data read-out, software updates, etc.
- 230V output for connection of level-dependent makeup/degassing stations
- Main switch on housing exterior
- Pump control
- Cable management for external connections
- Mounting slot for optional modules
Control unit completely piped and wired ready for connection according to VDE regulations. System connections by means of integrated shut-off valves.
Functioning of the pressurisation in the limits +/- 0.2 bar including pump monitoring. Optimised system water degassing due to patented, fully-automatic overflow control with cycles for continuous, interval and run-on degassing. Controlled make-up, automatic interruption and fault message upon exceeding of the runtime and/or the number of cycles. Processing of the signal of a contact water meter for maximum volume limit and/or capacity evaluation of ion exchangers located in the make-up line. Documentation and control of the entire system in respect of the above mentioned parameters.

7945600 - Commissioning Cat. 1
commissioning category 1 for a standard system in the product ranges Reflexomat, Variomat or Servitec incl. primary vessel and water make-up unit by the customer service, comprising:
- without travel and departure expenses,
- Adjustment of system to the operating parameters specified by the client,
- Checking the settings and operating parameters, and the system's performance and function in the overall system,
- Fillsoft and Fillset are checked too
- All set values documented in a report.
- electrical and hydraulic connection of the control unit, the accessory components and filled supply system.
- The expansion vessels of the pressurisation station must not be filled with water.
- A sufficient supply of filling water must be provided.
While it is entirely possible for customers to put a recently purchased system into service themselves, there are a number of reasons why commissioning by Reflex is a better idea.
- Certainty that the system is set up for optimum operation
- Excluding of possible damage due to incorrect commissioning thus reliability and avoidance of time and costs for downtimes
the service can take place within the local country inside about three weeks, internationally within about six weeks after placing of the corresponding order.
Services provided by Service are net! The price does not include any site waiting times or work arising from improper installation or improper condition.
Programming of the expansion and bus modules does not form part of commissioning. Programming is billed separately based on time and expenditure.
7859100 - Master-Slave Connect
Expansion option for Variomat pressurisation systems with Control Basic or touch controller.
For balanced, optimised operation of up to 10 Variomat/Variomat Giga in one network. All connected devices must have this control option available.
Separation between devices <1,000 m.
8997705 - I/O module VS
Extension for Reflexomat, Variomat and Servitec control units.
With two isolating amplifiers for the analogue signals from pressure and level measurement. Six digital input contacts and six potential free output contacts for processing messages and alarms. All housed in a dedicated plastic casing for direct integration into the associated control unit or, optionally, for Wall mounting.
Detailed description:
- Digital input: – freely configurable, 6 inputs, of which 3 are normally open, 24 V internal potential, standard configuration, e.g. for external temperature monitoring, minimum pressure signal, manual make-up, and 3 as normally closed contacts, 230 V external potential. Standard configuration as normally open contacts, e.g. for emergency stop, manual mode for operation of Pump/compressor, manual mode for operation of overflow device.
- Digital output: - 6 freely configurable potential free change-over contacts, standard configuration, e.g. for signalling make-up water faults, minimum pressure not reached, exceeding the maximum pressure, or manual/stop operating mode.
All the above contacts can be freely configured by the Reflex service team in accordance with the available information.
Assembly: The plastic control cabinet housing can be fitted into the designated mounting space of the control unit, as an alternative to on-site Wall mounting or installation in other control cabinets.
Wiring to the control unit is also carried out on the part of the building site.
9118042 - bus module Profibus DP Touch
Bus module for converting information, such as operating status or data, from the control interface of Variomat, Reflexomat or Servitec – available as a Compact Module for use with the Control Touch controller – into a data telegram.Direct integration onto the Control Touch control board. It is not necessary to perform additional assembly. Connection to the Control Touch via a plug socket.Installed in the controller housing of the Control Touch as an integrated extension module. On the Profibus side an RS 485 interface is available. Remote control of the following functions and parameters from higher level building management system:
- Pump/compressor 1 on
- Pump/compressor 1 off
- Pump/compressor 2 on
- Pump/compressor 2 off
- Overflow valve 1 open
- Overflow valve 1 closed
- Overflow valve 2 open
- Overflow valve 2 closed
- Make-up open
- Make-up closed
- Pressure specification p0 (pressure in 1/10 bar)
8860300 - bus module Ethernet
Bus module for conversion of the information such as operating status or variable network parameters from the control interface (RS 485) of Variomat, Reflexomat or Servitec with Control Basic or Touch controller into the data telegram.Everything in its own plastic housing for direct integration in the corresponding control unit or optionally for wall mounting.Installation:
Plastic switch cabinet housing can be inserted in the provided mounting slot of the control unit, as an alternative to on site wall mounting or installation in other switch cabinets.The wiring to the control unit is likewise performed on site. Commissioning and wiring does not form part of the scope of delivery
The cable connection to the microprocessor control unit includes its RS 485 interfaces and must be site-provided analogously to the power supply.The cable connection to the microprocessor control unit includes its RS 485 interfaces and must be site-provided analogously to the power supply.On the Ethernet side an RJ 45 connector is available for on site connection to a 100-Base TX network. Data exchange can be called up via Ethernet/IP, Modbus/TCP and HTTP protocols. Likewise the representation of the report html page.
