M-K/U expansion automats for system over 110° C according EN 12953-6 2011.
Installation and operating instructions
This manual describes how Flamco expansion automats could be used in heating systems where the Boiler supply line temperature is exceeding 110°C according EN 12953-6 2011 and is therefore applicable for Europe.
This instruction is a supplement to the main Installation and Operating instructions: Flamcomat G3/G4 and Flexcon M-K/U, see DocFinder www.flamcogroup.com.
Suitable for Flamco controlers
Flextronic:
-
The Flextronic controller is plug-and-play ready for >110°C applications.
-
Next to the hydraulic layout and sensors on the next pages, there is also a failsafe boiler cut-off output that must be connected according EN 12953-6 2011.
-
[Art.: 17504] Kit with plug-and-play connection piece with Temperature limiter, Minimal pressure limiter and
wiring. -
[Art.: 22386] Membrane rupture sensor is Flamco advised to use together with the >110°C kit.
Settings and terminal connections are mentioned in the Quick Start Guides delivered with our products.
SPC:
- The SPC controller can be used with the same sensors and kit mentioned for the Flextronic, but has no boiler
- Upgrade with a Flextronic retrofit kit.
- Provide a fail save boiler cut-off connected to the general fault terminals of the SPC.
Settings and terminal connections are mentioned in the Quick Start Guides delivered with our products.
The general fault connection (terminals 13-14) will open when there is an
error/problem in the heating system or automat. This is an normaly Closed (NC)
contact that will also open in case off power loss or broken controller.
Minimal faults that must be activated in [MENU 8-4] of the SPC-controller:
- Pressure (standard setting)
- Level vessel (standard setting)
- Diaph. rupture (only when this option is installed)
- Min. Pressure limiter
- Temp. monitor
