Information

Since the zone becomes too warm, a controller is required that disables the heater when a setpoint is reached. We will implement a hysteresis controller with a setpoint of 295.15 +/- 1K (21-23°C). A temperature sensor will measure the zone air temperature.

Required models

• Modelica.Blocks.Logical.Hysteresis
• Modelica.Blocks.Logical.Not
• Modelica.Blocks.Math.BooleanToReal
• Modelica.Thermal.HeatTransfer.Sensors.TemperatureSensor

Connection instructions

The heater modulation level should be set to 1 when the heater is on and to 0 otherwise. Furthermore, the pump should only circulate water when the heater is on.

Reference result

The figure below shows the air temperature after the controller is added.
