To set the Setpoint Limit and Hold Time for thermostats:
Users can change the setpoint from a thermostat by pressing the up or down buttons. The System
Controller will limit how far they can change the setpoint based on the Setpoint Limit. In addition,
changes made to the setpoint at the thermostat will be cancelled after the Hold Time, at which point the
scheduled setpoint will resume.
1. On the Climate tab, select the desired thermostat under Thermostats in the tree structure.
2. Click the Setpoint Limit drop down, then select the desired number of degrees above and below the
schedule that users can change the setpoint.
3. Repeat for the Hold Time setting.
To specify and enable alerts:
The System Controller can be configured to provide alerts if the temperature at a thermostat is too high or
too low, or if a thermostat fails to respond.
NOTE: Alerts are sent out immediately for temperature conditions being above or below the specified
alarm. Alerts are also generated if a thermostat fails to communicate for 10 minutes.
NOTE: To receive email notifications for alerts, you must also configure the email settings as described
above in To set email settings for alerts.
1. On the Climate tab, select the desired thermostat under Thermostats in the tree structure.
2. Click the Low Temp Alarm drop down and then select the desired temperature from the list.
3. Repeat for the High Temp Alarm setting.
