Hi,

I wanted to know how cooling setpoint schedules worked with a 'Temperature' variable. Do the limits mean that indoor temperatures will always be between those limits regardless of the outdoor temperature?

For my example I need to have schedule for the air conditioners (split unit) in a office room, on - off, when they are on the room temperature goes down to approximately 20 C but when it is off I have no idea, i.e. it depends on how hot it is outside. Would this type of schedule suit or should I use something else such as an HVAC system representing a split system AC with a on/off schedule?

Any help would be very much appreciated!

Thermal zone thermostat setpoint schedules represent a target value, but the thermostat itself doesn't doesn't enforce that this happens. If you put a thermostat in an unconditioned (or under-conditioned) thermal zone and there are a lot of internal loads or severe outdoor temperatures, then the resulting thermal zone temperature could be outside of the target range. EnergyPlus will calculate impact of model and environmental elements at each timestep to calculate the actual zone temperature.

@David Goldwasser Thanks for the answer. So why would we use thermostat setpoint schedules?

It sets the value for set point for room temp in cooling /heating mode likes temperature on remote of split air conditioner. When room temperature is with in setpoint range, cooling coil (compressor/aircondtioner) will be turned off
