- Page 2 Introduction This setup tutorial will step through some of the main ways that the CT224 can be used. After completion, the user will have a good understanding of the features and how to use them. Each section will build off of the one before it.S...
- Page 3 16. Set “Zone to be displayed during normal operation” to “Any”, then press Enter. This will allow the user to choose the zone that will be displayed on the CT224. 17. Set “Minutes of Alarm Silence when a key is pressed” to 1 minute, then press Enter.
- Page 4 26. The display will read “Zone 1 Trip 2: Off”. Press & hold Enter until CT224 re- initializes the controller (about 3 seconds). 27. The current temp reading will now be displayed on the controller for Zone 1. 28. Heat the sensor until the alarm and output trip. (Hold onto the sensor to increase the temperature of the sensor or place inside of a plastic bag and then place the bag and sensor into a cup of warm water).
- Page 5 17. Set “Zone 1 Trip 1: Untrip Outputs by” to “Using Hysteresis”, then press Enter. 18. Set “Zone 1 Trip 1: Set Hysteresis:” to “5”, then press Enter. 19. The display will read “Zone 1 Trip 2: Off”. Press & hold Enter until CT224 re- initializes.
- Page 6 Output 1 set for reverse acting. Setting the output for reverse acting can be a good way to protect equipment in case of power interrupts to the CT224. You have now configured Zone 1 to trip on an under temp condition using hysteresis to untrip.
- Page 7 1. Press and hold any one of the keys on the front panel until the main menu is displayed. 2. Continue to set the settings from “Reverse Acting Outputs” to “Zone 1 Choose Input Type” as appropriate. 3. Set “Zone 1 Trip 1:” to 70º F, then press Enter.

- Page 9 8. Set “Zone 1 Trip 1: Set Hysteresis:” to “5”, then press Enter. 9. The display will read “Zone 1 Trip 2:” set to “Off”. 10. Press & hold Enter until CT224 re-initializes. 11. The current temp reading will now be displayed on the controller for Zone 1.
- Page 10 7. Set “Untrip Outputs by” to “Manual Reset Only”, then press Enter. 8. Set “Zone 1 Trip 1: Set Hysteresis:” to “5”, then press Enter. 9. The display will read “Zone 1 Trip 2: Off”. Press & hold Enter until CT224 re- initializes.
- Page 11 5. Set “Offset for Zone 1: 100 Tenths”. 6. Press & hold Enter until CT224 re-initializes and the CT224 will display Zone 1 with current temp reading 10º F above the actual temperature. You have now configured Zone 1 with an offset of 10º F. The offset will allow you to improve accuracy of the readings and allow you to minimize the error present.
- Page 12 2. Move the cursor to 4. “Options”, then press Enter. 3. Select 3. “Freeze Outputs”, and then Enter. 4. The CT224 will then return back to the Main Menu with the cursor at “Monitor Zones”, press Enter again. 5. The CT 224 will re-initialize and return to its normal operating mode, displaying “Outputs Are Frozen”.
- Page 13 When this section is exited, either due to the 60-second timeout or exited by the user, the CT224 will automatically reset and start scanning with the new program settings. The CT224 will also reset when program settings are changed via the communications link using MincoSoft’s CT224 Software.
- Page 14 Modbus address. The valid range of addresses is from 1 to 247. If 0 is selected, the CT224 will not monitor the communication lines. Each CT224 is factory set to a default Modbus address of 1. If communications are not used, it is acceptable to leave the default address at 1.
- Page 15 Due to the 60-second timeout in the CT224, it is best to fill out the Setup Worksheet before configuring the unit. This will also allow you to have record of the settings that are programmed into the unit for future reference.
- Page 16 Manual Reset Only – This setting causes the outputs to latch. The outputs can only be reset by entering the Main Menu and selecting Manual Reset. (A password may be necessary to reset the relays.) Pressing Enter – The outputs will untrip when Enter is pressed. Minco Tel: 763.571.3121 • Fax: 763.571.0927 • www.minco.com...
