The Viconics VT7600F controller has the ability to maintain a minimum heating supply
temperature by using an analog 0-10VDC proportional output instead of using the staging
outputs which will cause the unit to cycle. Using a full proportional output to maintain the
minimum heating supply temperature can increase cost savings and less wear and tear
on HVAC equipment.
The desired minimum setpoint temperature value can be set under the Min SH parameter
and the following conditions must apply:
- The system mode is heating.
- The occupancy mode is in Occupied or Temporary Override.
- The OA temperature value is below SH lockout parameter value.
