Certification program is intended for those interested in Unipi partnership programme. The certification is contingent upon completing a certification task in the form of a practical automation solution using the Unipi certification kit.
Experienced Mervis users do not have to undertake the certification test. If your company have already finished one or more Mervis projects, you can obtain the certification by sending us one of your completed projects.
Your task is to create a system for controlling heating and lighting in a single room. All required components are contained in the certification kit. Start with building the kit, using this connection scheme as a guide.
Assembly of the certification kit:
Fasten DIN rail holders to both the Patron S107 unit and the xS11 extension module using the provided screws
Mount the units, terminals and relays to the DIN rail according to
this scheme Interconnect blue terminals with the 2-way jumper
Interconnect red and grey terminals with the 3-way jumper
Insert the resistance housing into the grey terminal
Connect all cables and conductors according to
the scheme Before connecting the power source, check the correct voltage polarity
Room heating control consists of:
Controlling a heater using relay (RE2)
Temperature measurement using the PT1000 resistance thermometer
Using a programmable week scheduler for setting the required temperature
An option to manually adjust the temperature by +-3°C using the potentiometer
Displaying a current and adjusted required temperature through a web HMI
Displaying a current heater status through a web HMI
Lighting control consists of:
Control of a single lighting circuit through a relay (RE1)
Physical lighting control using the red button
Lighting control using a web HMI
Recommended methods:
Implement the hysteresis control (“On-Off Control - Heating (B31)” block)
Use “Real Scheduler (T18)” block for creating the timetable
Transform the potentiometer output value to 3-/+3 using a linear transformation
Connect the lighting control button to the relay using the Direct Switch Toggle function
For simultaneous control of the Direct Switch output, use the Force Output register
Encapsulate the whole solution into a single function block for better convenience
