Dimensions and installation
Installation precautions
- Ensure the panel's thickness is between 1/32 in. and 1/16 in. (0.8 mm and 2.0 mm).
- Ensure that the working conditions are within the limits stated in
specifications.
- Do not install the controller close to heat sources, equipment with a strong magnetic
field, in places subject to direct sunlight, rain, dampness, excessive dust, mechanical
vibrations, or shocks.
- Install the controller in compliance with safety regulations to ensure adequate
protection from contact with electrical parts. Fix all protective parts in such a way that
you need a tool to remove them.
Dimensions are in mm (in.). Fit the controller to a panel with the supplied snap-in brackets.
Wiring
Important
- Use cables with an adequate cross section for the current that runs through them.
- Connect the power cables as far away as possible from the signal cables, to reduce
electromagnetic interference.
Wiring precautions
- If you use an electrical or pneumatic screwdriver, adjust the torque to a maximum of 4
in. lb (0.5 N•m).
- If you move the controller from a cold to a warm place, the humidity may cause
condensation to form inside. Wait an hour before you switch on the power.
- Make sure that the supply voltage, electrical frequency, and power are within the set
limits. See Technical specifications.
- Disconnect the power supply before you perform any type of maintenance.
- Do not use the controller as a safety device.
- For repairs and for further information, contact the PENN sales network.
First time setup
Note: The default password for the controller is -19.
1. Install the controller in the panel. See Dimensions and
2. Wire power to the controller. See the power supply terminal in Wiring.
3. Tap On/Standby to turn on the controller. An internal test runs for several seconds.
After the internal test, the display switches off.
4. Configure the controller. See Setting configuration parameters
following list contains some useful parameters to configure for first time setup:
- Setpoint (SP), default: 32
- Temperature unit of measurement (P2), default: °F
- Defrost type (d1), default: electric
Note: Check that the remaining settings are also appropriate. See
parameters.
5. Disconnect the controller from the power supply.
6. Make the electrical connections without powering up the controller. See Wiring.
7. Reconnect the power supply.
8. Tap On/Standby to turn on the controller.
4 User interface and main functions
Switching the controller on or off
If POF is set to 1, tap the On/Standby key for 4 s. See
configuration parameters.
When the controller is switched on, the display shows the value that the parameter P5
indicates. P5 is set to cabinet temperature by default. If the display shows an alarm code, see
Alarms.

Activating manual defrost
1. Check that parameter r5 is set to 0 for cooling. r5 is set to 0 by default. See
Setting configuration
2. Press the Up or Defrost key for 2 s.
Note: If P4 is set to 1, defrost only activates if the evaporator temperature is lower than the
d2 threshold. P4 is set to 1 by default.
Switching the cabinet light on and off
You can switch the K2 relay on or off if you configure and wire it for a cabinet light or a button-
operated load.
1. Check that parameter u0 is set to 3 for cabinet light, or 1 for button-operated
load. u0 is set to 3 by default. See
