mPID4 series
Programmable control unit - mPID4 Series
Panel controller with or without graphic display, equipped with two Modbus serial ports for communication with in-field controllers and the supervision module. It allows multizone systems to be managed with sophisticated special programmable functions and up to 4 settable time programs. Through mPID4 it is possible to control the treatment (dehumidification and integration) and air renewal units, the radiant system and other accessories on request. Several digital and analog inputs and outputs and a modular configuration allow functions to be extended to medium-high complexity systems.
Available in three versions:
• DSP: version with graphic display through which all the module functions can be locally controlled and the desired system operation set;
• CLT: version without display, used as an expansion to the Master DSP module, should the number of inputs and outputs be not sufficient for system requirements
• EXP4: version without display, used as an oversized expansion to the Master DSP module, with more inputs and outputs than CLT
The module is fully programmable according to customer’s system requirements.
A layout example is given below:
Universal Inputs:
• U1 – Mixed circuit delivery temperature probe
• U2 – External temperature probe
Digital outputs:
• K1 – zone 1 heads
• K2 – zone 2 heads
• K3 – zone 3 heads
• K4 – zone 4 heads
• K5 – booster pump control
• K6 – dehumidification control
• K7 – integration control
• K8 – generator control
Analog Outputs:
• Y1 – Mixing valve control
