As I have understand the right application for my two regulations are not pre-programmed on RLUs. Have somebody a little time do help me with some tricks to get the first steps in this world? Apreciated (very) any document that describe how to write free control loops in these devices. If is needed I'll describe the two regulations loops with the entire process datas (they're very easy). thanks in advance

This guide will help you to understand how it work's. There is also a basic documentation for the Synco 200 controller (to big to send in this forum), you certainly will find as dowload in the internet, if not let me know, we'll find a solution.

Control Loop 1: Controller: RLU 222 Brief description: the 3-way valve must be closed if temperature of water is =< 60° and fully open when water temperature is =>61° (theoretically, but suspect tha in practice the band of control loop need do be at least 5° ...) - TEMPERATURE SENSOR FLOW: SIEMENS QUAE2120.010 - WATER TANK 1000 L - WATER IN WOOD BOILER 83 LT - PUMP SUPPLY 4500 l / h (nominal) - OPPORTUNITY 'TO BLOCK THE ADJUSTMENT WHEN THE WOOD BOILER IS OFF - POSSIBILITY FOR A SIGNAL VALVE FULLY OPEN TO TANK - OPENING TEMPERATURE 60-65 ° - ACTUATOR SQK33.00 Control Loop 2: Controller: RLU 236 Bried description: the proportional valve need to regulater floor heating panels, it's needed outside compensation and a valve closing input (when both room thermostats give an off signal) - TEMPERATURE SENSOR FLOW: SIEMENS QUAE2120.010 - EXTERNAL SENSOR CLIMATE: SIEMENS QAC22 - WATER TANK 1000 LT A 80 ° (46 ° IN A METHANE OPERATION ) - WATER IN A PANEL 100 LT 30-35 ° - PUMP SUPPLY 8000 l / h - TWO AREAS WITH BY-PASS VALVE WITH CONSENT FOR THE PUMP - OPPORTUNITY 'TO BLOCK THE ADJUSTMENT WHEN THE PUMPS ARE OFF - POSSIBILITY FOR A SIGNAL FLOW TEMPERATURE CORRECT - ACTUATOR SQS65

Where are the parameter for control loop such as gains and deadband? Regards

The set points are in the menu SET.I propose to set the set point “sun” cool to 60°, for this you have to change also the set point “mond” to 62°. In the PARA of the CTLOOP1 set the SEQ4 XP to 1 and the SEQ4 TN to 00:30.If the reaction of the valve is to fast set th XP to 2 and TN to 1:00 but this depend on your hydraulic configuration. Regards Richard

Your is a good start, even that I've 3P valve, the actuator SQK33.00 is 3P. Yesterday evening I've looked around and I've see about U09 could be that's right, with the adjustment of CTLOOP1? I understand that for who is inside this world is very simple, but from outside these are a very black-box :D Regards Gabriele

But you don't have anymore acommand for the pump. As attachment the basic documentation of theRLU controller. Hope this will help.
