9.10.4 Email Message
The MCT provides the user with the ability to send short email messages to users configured in the MCT email
server. To send a message, select “Message” from the device settings, Email menu.
Press the “Compose” button to create a brief message using the keypad (up to 100 characters). When you are
finished entering the message, press the “Done” button. The completed message will then be shown in the
message window. Press the “Send” button to select the email recipients you wish to receive the message and
send the message.
9.11 Tuning
The loop Tuning screen allows for manual and automatic tuning of the MCT control loops. Tuning parameters
should only be manually adjusted by skilled users familiar with proportional control. Improper settings can result
in control loop instability and equipment damage. The loop automatic tune function is the recommended method
of loop tuning. If the control response achieved after performing an auto tune does not provide the desired
control response, then minor adjustment of the tuning parameters may be done manually to obtain the desired
response.
The available tuning parameters are dependent upon the loop configuration. If programmed for heat or cool
only control, then the available parameters will be PB (proportional band), TI (integral time period) and TD
(derivative time period). If the loop is configured for heat/cool operation then two additional parameters for
Cooling PB (cooling proportional band) and Dead Band (heat/cool dead band) will be provided.
The tune screen also provides a live real time chart for monitoring the control response of the control loop while
adjusting tuning parameters. The chart is fixed at a 10-minute time period and updates once per second.
