Installing and Operating Instructions

12. HOW TO USE THE HOT KEY

12.1 HOW TO PROGRAM A HOT KEY FROM THE INSTRUMENT (UPLOAD)

Program one controller with the front keypad.

When the controller is ON, insert the "Hot key" and push o key; the "uPL" message

appears followed a by flashing "End"

Push "SET" key and the End will stop flashing.

Turn OFF the instrument remove the "Hot Key", then turn it ON again.

NOTE: the "Err" message is displayed for failed programming. In this case push again o key if you

want to restart the upload again or remove the "Hot key" to abort the operation.

12.2 HOW TO PROGRAM AN INSTRUMENT USING A HOT KEY

(DOWNLOAD)

Turn OFF the instrument.

Insert a programmed "Hot Key" into the 5 PIN receptacle and then turn the Controller ON.

Automatically the parameter list of the "Hot Key" is downloaded into the Controller memory,

the "doL" message is blinking followed a by flashing "End".

After 10 seconds the instrument will restart working with the new parameters.

Remove the "Hot Key"..

NOTE the message "Err" is displayed for failed programming. In this case turn the unit off and then

on if you want to restart the download again or remove the "Hot key" to abort the operation.

13. ALARM SIGNALS

Message

Cause

"P1"

Room probe failure

"P2"

Evaporator probe failure

"HA"

Maximum temperature alarm

"LA"

Minimum temperature alarm

13.1 ALARM RECOVERY

Probe alarms P1", "P2", start some seconds after the fault in the related probe; they automatically

stop some seconds after the probe restarts normal operation. Check connections before replacing

the probe. Temperature alarms "HA", "LA" automatically stop as soon as the temperature returns to

normal values.
