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
