Information

This model is used for the basic test case 640 of the BESTEST validation suite. Case640 is the same as Case600, but with the following modifications:

From 23h00 hours to 07h00 hours, heat = on if zone temperature is below 10°C
From 07h00 hours to 08h00 hours, the thermostat setpoint shall vary linearly with time from 10 °C to 20 °C. If the zone temperature is less than the thermostat setpoint for a subhourly time step, heat shall be added to the zone such that the zone temperature at the end of each subhourly time step shall correspond to the thermostat setpoint that occurs at the end of each subhourly time step.
From 08h00 hours to 23h00 hours, heat = on if zone temperature is below 20°C
All hours, cool = on if zone temperature above 27°C
Otherwise, mechanical equipment is off.
