This Quick Start Up section is designed to get you up and running with the minimum of fuss. Just follow these 6 simple
steps.
STEP 1
-
Using the table below, decide which type of controller you wish the Universal-R to
function as and take note of the required setting for parameter “tC”
Also take note of the number of probes to be connected.
Paramete
r “tC”
setting
Type of Control Number
of probes
required
1
On / Off thermostat – Cooling
x 1
2
Off cycle defrost (timed)
x 1
3
Electrical / Hot Gas defrost, time initiated / time terminated
x 1
4
Electrical / Hot Gas defrost, time initiated / temperature terminated
x 2
5
Electrical / Hot Gas defrost, time initiated / temperature terminated + evap. fan delay
x 2
6
On / Off thermostat – Heating
x 1
Note: “tC” settings 3, 4 & 5, default to Electrical Defrost. Hot Gas is possible by setting parameter “tdF” for gas defrost.
Settings 1,2,3 & 6 do not require the 2
nd
probe to be fitted
STEP 2 - Install the new Universal-R and connect up the wiring and probe(s).
If in doubt, refer to Section on typical wiring connections
STEP 3 - Turn on the power supply to the controller
For 1 minute, you now have direct access (without pass code) to parameter “tC” and to start the automatic probe type
recognition, after which these parameter settings will have to be done manually and the pass code will have to be
entered.
STEP 4 - Within 1 minute from the power on, press the n button for 3 seconds, the
controller will automatically recognise if the probes connected to it are PTC or NTC. During
recognition time the controller will display: tPd (type of probe detection) followed by the
kind of probe “ntc” or “Ptc” flashing for few seconds.
Notes: Probe temperature must be between –50c & + 60c for automatic probe recognition to work correctly
When using 2 x probes, both must be the same type, you cannot mix them.
STEP 5 – Within 1 minute from the power on, press the “SET + n ” buttons for 3 seconds
and the label “Pr2” will be shown, release the buttons and parameter “tC” will be
displayed, then press the “SET” button again to see the current setting and adjust using the
o & n buttons to the setting you require for your particular application.
Allow display to return to normal
STEP 6 - Press the “SET” button for 3 seconds until the small LED’s at the top of the
display start to flash and the Set Point value is displayed, then adjust the “Set Point” using
the o & n buttons.
IMPORTANT: Finally turn off the power then turn back on again
We recommend you you check the parameter default settings listed in these instructions to ensure they suit your
particular application. If you need to make further parameter adjustments or you require more information, read the
