meitav-tec PS-4500-P-3S-FC-Super Product information

  • Hello! I've analyzed the provided datasheet for the meitav-tec Controller PS4500-P-3S-FC-SUPER and its compatible wall panels. This document details the wiring, configuration, and operational modes. It covers aspects like sensor connections, jumper settings for different system types, and fan control behaviors. I am ready to assist you with any questions you might have about this device and its features.
  • What should I do before making any changes to the unit?
    When is the pump output active?
    What happens if the occupancy sensor is not connected?

Indoor Coil Sensor
F5 – Short – Fan Only mode available
(Selectable through thermostat)
F5 – Open – Fan Only mode not available
Indoor Coil Sensor (T3) Indoor
Fan in heat mode
Auto Fan = ON :
With Indoor Coil Sensor
T3 > 36ºC → Fan ON
T3 < 32ºC → Fan OFF
Without Indoor Coil Sensor
The Indoor Fan will operate when
there is a demand for heating (with
30 seconds time delay)
Jumpers – JP4 & JP5
JP4 – SHORT (4-Pipe System)
Auto change over active
2 separate outputs for Cool and Heat
T2 – for monitoring only
JP4 – OPEN (2-Pipe System)
Auto change over not active
1 output for Cool and Heat
T2 – Logic selection

Occupancy Sensor
When the IR (N.C.)
input is open for 10
minutes, all outputs
turn Off.
Short the (-12V) and
(IR) connectors, only
when an occupancy
sensor is not
connected
Change Over Sensor (T2) in 2-
Pipe system:
With Change Over Sensor
T2 < 20ºC → Cool
T2 > 30ºC → Heat
Without Change Over Sensor
Manually select the mode using
the wall panel or computer.
F4 – Fault 1 input (N.C.)
When open – all outputs OFF (no delay)
F6 – Fault 2 input (N.C.)
Only for indication through the protocol
Not in use
