7.10 Checking control inputs and outputs

7.10.1 Functional input
120
The MATRIX 500/3000/4000 control systems are fitted with inputs and/or out-
puts.Consider the factory-performed configuration for checking control inputs and
outputs.Refer to the unit connection diagram (attached to the connection box) for
the relevant controller function.
Field-performed changes of the configuration (via MATRIX.PDA service tool or
MATRIX.PC service software) have to be considered separately (not with
MATRIX 511).
Depending on the control system, the input can be assigned with the following
functions as required:
Window contact (unit OFF with room frost protection); (not with MATRIX
511)
• Couple input terminals.
• Turn the unit on and adjust the setpoint as required to activate the fan.
• Remove the jumper.
The fan must switch off, the valves close
(unit remains in frost-protection monitoring mode).
Economy mode
• Turn the unit on and adjust the setpoint as required to activate the fan.
• Couple input terminals.
The fan must switch off and valves close.
Requirement: economy mode setpoint adjusted accordingly (unit continues to
operate in frost protection monitoring mode, if this function is available).
NOTICE!
If multiple inputs of different configuration are used within one group, then
"economy mode" input has priority over "window contact" input.
