Icon Electronics D3-TCT1 User manual

Description:
This device incorporates a digital temperature controller and a 24 hour timer. These functions operate
independently and control separate relays.
The settings may be locked and code protected to avoid changes from being made by unauthorized personnel.
Operation:
Timer Relay:
Whenever the current time (time of day) falls between the “ON” and “OFF” times, the timer relay is energized.
Note that there are 2 “ON” and “OFF” times.
A manual override function is included to force the timer relay to remain energized for up to 24 hours.
Adjustable parameters: Please note: Depending on the model of the device purchased, some of the parameters listed below
may not be available
• Pre-set temperature “°C” (default value: 25.0)
When the probe temperature reaches this value, the relay is de-energized.
• Clock setting “CLOC”
Set this value to match the current time.
• Manual override “Ourr”
Set the amount of time the relay must remain energized. This value is decremented every minute. When it
reaches zero, the relay will revert to the pre-set on and off times.
• On time 1 “On 1”
Use this setting to adjust when the timer relay will energize.
• OFF time 1 “OF 1”
Use this setting to adjust when the timer relay will de-energize.

• On time 2 “On 2”
Use this setting to adjust when the timer relay will energize.
• OFF time 2 “OF 2”
Use this setting to adjust when the timer relay will de-energize.
•
Hysterises “HYSt” (default value : 1.0 ºC)
Once the relay has de-energized, the temperature must change by this amount before the relay will re-energize
• Reset (“rESt”)
Selecting this menu option resets all values to default press “+” & “-” or (“T” and “S”) to confirm reset.
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.
