1.2 Benefits of Cheops Control
• Continuous P/PI room temperature control
• Heating mode + actuation of a cooling system via the EIB
• Alternative actuation of a second heating step with switching or continuous actuating
value
• 2 buttons for set point offset (up to +/- 3K)
• Infinite valve adjustment through continuous actuating value
• Internal temperature measurement possible via either EIB or an external temperature
sensor
• Valve position or set point value offset readout
• Emergency program on actual value failure
• Establishing the maximum actuating value
• Valve protection program
• External interface for window and presence contacts
• Actuating value limitation
• Precise adjustment to each valve
• Operation with both standard and inverted valves
• Site function for operation without application
• Large valve stroke enables adjustment to almost all valves
• Simple assembly with any valve adapter
1.2.1 Special features
• Monitoring of actual value
If the room temperature is measured via an external sensor or received via an object, Cheops
control can start an emergency program if the sensor or temperature transmitter fails.
• Determining the maximum actuating value (= maximum position)
To adapt the forward flow temperature, Cheops drive can send an acknowledgement to the
heating boiler regarding the current power requirement.
This can reduce its temperature if the requirement drops.
• Window and presence contact inputs
Cheops drive has 2 external inputs, one for a presence contact and
one for a window contact. These inputs can be used as an actuator for frost protection or
comfort mode.
