Description:
This device offers 0.1 degree resolution, adjustable offset, hysteresis and upper and lower limits for the pre-set
temperature setting. It can be configured for heating or cooling applications. The settings may be locked and code
protected to avoid changes from being made by unauthorized personnel.
Operation:
Heating mode:
Temperature must rise to set point value before relay de-energizes, then it must drop by the hysteresis amount
before being re-energized.
Cooling mode:
Temperature must drop to set point value before relay de-energizes, then it must rise by the hysteresis amount
before being re-energized.
Menu operation:
Press the “MENU” button repeatedly until the desired setting is reached, press “SELECT” to display the current
value.
Use “+” and “-” buttons to change the value. “ENTER” will return the device to the menu. The “BACK” button will
exit the menu.
Adjustable parameters:
1. Pre-set temperature “°C” (default value: 25.0)
When the probe temperature reaches this value, the relay is de-energized.
2. Hysteresis “HySt” (default value: 1.0, range 0-100.0 °C )
Once the pre-set temperature has been reached (and the relay has de-energized), it must change (in the
opposite direction) by this amount before the relay is re-energized.
3-4. Maximum “Hi” and minimum “LO” user setting
(Default value: 45.0, -10.0)
These are the upper and lower limits obtainable via the set point (setting number 1 “°C”).
5. Relay function “Func” (default: Heating)
Type of elements connected to the relays:
“HEAT” both relays are used with heating elements.
“COOL” both relays are used with cooling elements.
6. Offset “OFSt” (default value: 0.0, range -10.0 to +10.0 °C)
This value is added (or subtracted if negative) to the current temperature.
7. Reset “RESt”
By selecting this setting, the device is reset to the factory defaults

Menu options:
Exit the menu before making the following adjustments.
Lock / unlock parameters: (default: unlocked)
Press “BACK”, then “ENTER” and hold the 2 buttons until the desired option is displayed. The display cycles
between “Loc” (no changes allowed) & “u.Loc” (parameters may be adjusted)
Full / reduced menu (default: Full)
Press “SELECT”, then “ENTER” and hold the 2 buttons until the desired option is displayed. The display cycles
between “rEdu” (limited menu) & “Full” (all parameters are accessible)
Access Code: (default: no code)
Once the above options have been set as required, Press “BACK” and “SELECT” simultaneously until “CODE” is
displayed. Now use the “+” & “-” to enter a code.
Once a code is entered, access to the options above is not permitted. To clear the code, re-enter the same code
again. If the code is forgotten. Press and hold “+” & “-” until “CODE” is displayed while re-applying power to the
device.
Notes:
1. The display will show “Err” if the sensor is not connected correctly, or is faulty.
2. To avoid damage to the sensor, ensure that it is connected correctly before applying power.
Menu operation example: Set the temperature to 30.0 °C:
Press “MENU” to display “°C”. Press “SELECT” to view the current value. Use the “+” and “-” buttons to change the
value to 30.0. Press “ENTER” to return to the menu. Press “BACK” to exit the menu.
