Note
Important information to the section in the manual.
Uponor uses safety messages in the document to indicate special precautions required for the installation and operation of any Uponor product.

System description

Always use the specified combination of heating blanket and pipe dimension.
Never use a heating blanket (i.e. 160 mm) for a smaller pipe dimension (i.e. d =125 mm). It will overheat the pipe and damage the pipe surface.

The Uponor Ecoflex heating blanket can heat up the Uponor Ecoflex pipe ends to soften them for the fitting installation.
The Uponor Ecoflex heating blanket set contains:

• a controller with a large LCD display
• a flexible heating blanket, available for the pipe dimensions 125 mm, 140 mm or 160 mm

Uponor supplies one set per dimension. The heating blankets are hard-wired to the controller.

Components

Controller

Main characteristics:

• Large, illuminated LCD display
• Membrane keypad, easy to operate
• Cycle timer with user selectable, delayed start

Heating blanket

Main characteristics:

• Flexible and lightweight
• Fixing straps with hook-and-loop-fastener
• Even heating
• Moisture and chemical resistant
• VDE approved

Operation

Power On/Off

Note
The temperature controller does not have an On/Off-switch.
Pressing the standby key will do following:

• put the controller into standby mode
• turn off the display backlight
• stop the temperature control function

Controller settings

Adjust all controller settings with the membrane keypad on the front panel.

Main screen

The main screen shows the actual temperature of the sensor inside the heating blanket.

Set-point temperature

To adjust the set-point temperature, change to the set-point screen:

1. Press and hold the up/down key for 2 seconds, while the display shows the main screen, until "SET-POINT" appears on it.
2. Use the up/ down key to adjust the required temperature.
3. Press and hold the up/ down key for approximately 5 seconds to return to the main screen and to see the current process temperature.

Settings menu

Note
If no key is pressed for at least 10 seconds while the controller is in one of the setting menus, the display will return to the main screen.

To move the setting indicator (little arrow) to each menu item in turn, press the menu key subsequently. If the menu key is pressed while the arrow points to the "Units" option, the controller will return to the main screen.
When the up/ down key is pressed while the settings menu is active, the item the arrow points to can be edited.

Timer settings

Timer hold
Note
If "hold" is selected the timer will not start until the temperature set point is reached. If "hold" is unselected the timer will begin as soon as the controller returns to run mode.
To use the "Timer hold" function obey the following steps:

1. Press the menu key to move the arrow to the "hold" box.
2. To activate or inactivate the "Timer hold" function use the up/ down keys.

Timer enabled
Note
Always activate "Timer en" when you want to use the "Timer hold" function!
Note
If "Timer en" is selected while "Timer hold" is unselected the countdown will start even if the set point temperature is not reached yet.

To use the "Timer en" function obey the following steps:

1. Press the menu key to move the arrow to the "en" box.
2. To activate or inactivate the "Timer en" function use the up/ down keys.

The timer period is displayed in the top left corner of the main screen while the timer is enabled. If "Timer hold" and "Timer en" are enabled at the same time the display will show a "h" next to the timer until the countdown starts.
After the timer countdown has ended the heating mode is turned off automatically and the controller is going back to standby mode.
In both modes the colon between the hours and the minutes will flash to indicate that the timer is running.

Timer completed
After the countdown stops, following things will happen simultaneously:

• The temperature control function will stop.
• The display will start to flash and show "Timer Complete!".

Timer restart

To restart the timer or to revert to standard mode, press the menu key from the "Timer Complete!" screen.
The "RESTART TIMER" option will start the heating cycle with the same settings as before.
The "REVERT TO STANDARD MODE" option will reset the settings from the cycle before and the controller will return to standard mode.
To change between both options, press the up/ down key. Enter each option by pressing the menu key.

Hysteresis

Note
Selecting a lower value for the hysteresis will give a better accuracy for the set-point temperature, but the heater will be turned on and off more often. This can reduce the life time of the relay. If accuracy is less important it is recommended to use a higher value.

The hysteresis is the difference (in degrees) between switch-on and switch-off temperature during the heating mode.
The heat up period will stop at the set-point temperature. It will be switched on again at the set-point temperature minus the hysteresis value. The hysteresis range is adjustable between 1 and 9. The default value is 5.
While the arrow on the display points to the Hysteresis option, use the up/ down keys to change the value.

Offset value

Note
In some situations the actual temperature of the product being heated may differ due to higher or lower heat losses.
The offset value is used to correct the difference between the temperature displayed and the actual temperature of the product being heated. This difference can occur because the sensor of the controller is attached directly to the heater.
The offset value can be adjusted between -10 and +10, but the value required can only be found by testing in the given situation.
While the arrow on the display points to the offset option, use the up/ down keys to change the value.

Unit settings

While the arrow on the display points to the units option, use the up/ down keys to change the setting between °C (Celsius) and °F (Fahrenheit).
Pressing the menu key at this point will return the controller to the main screen.

Standby

Pressing the standby key for 2 seconds will put the controller into standby mode. The display will show "STANDBY".
The temperature control function will stop and the display backlight goes dark.
Pressing the standby key while the controller is in standby mode will turn the backlight on again and the controller will return to the main screen.

Display contrast

While the controller is in standby mode the contrast of the display can be changed using the up/ down keys.
