From the , you can configure proportional cooling. The cooling coil output modulates to maintain zone temperature. The output ranges from 0% to 100% based on demand. menu ,you can also set the discharge low limit parameter. If the discharge falls below a Supply Air Setpoint Cooling Min parameter, which is initially set to 50°F, cooling slows or stops.
For more information about commissioning cooling, see Table 1.
If OAT Cooling Lockout is enabled, you can define a OA Cooling Lockout Setpoint to disable the cooling if OA-T is less than the OA Cooling Lockout Setpoint. You can define a FailSoft cooling value to place the cooling valve in this position when there is a low limit alarm.
