Control Functions

The controller is designed to control binary heating and/or cooling systems.

Setpoint

• Minimum and Maximum Set Point Limits: Limits the adjustable range of the loop set point. The limits for heating and cooling sequence may be chosen individually.

Control Sequence

• 4-pipe or 2-pipe system: 4-pipe systems use one heating and one cooling stage. Heating and cooling mode will switch according to demand. A delay is implemented to prevent unnecessary switching between heating and cooling mode: Heat – Cool change over delay. To disable the automatic switching set UP03 to OFF.

• Economy set point shift X

heating set point W shift X

• Dead Zone Span X

change the heating or cooling set points within adjustab le limits.

• Switching Hysteresis: Defines the difference between switching on and switching off of an output. A small hysteresis will increase the number of switching cycles and thus the wear on associated equipment.

• Switching Span: Defines the temperature difference required to switch on the next stage in case multiple stages are active (2-pipe system only).

• Delay OFF: Prevents a too short running cycle for the heating or cooling stage by setting a minimum running time. Delay OFF applies to all heating and cooling stages.

• Delay ON: Prevents a too short stopping cycle for heating or cooling stage by setting a minimum stopping time. Delay ON applies to all heating and cooling stages.

• Step by step switching: In order to reduce the startup load of large motors, multiple stages will be switched on and off step by step.

Output Configuration

Two options are available: 3-point or binary.

3-point output

If 3-point is selected a 3-point actuator may be driven. The actuator has an open input and a close input. Applying power to the Open input will drive the valve or damper open, applying power to the close input will drive the valve or damper to the closed position. The running time of the actuator may be preset. We recommend to enter the maximum running time under maximum load in order to make sure that the valve can fully close and fully open in any circumstance.

In order to open the valve or damper DO1 will be activated for the preset amount of time. After the expiration of the running time DO1 and DO2 will be OFF. The valve is closed by activating DO2 for the preset amount of time.

Binary output

Two devices may be controlled in case the 3-point actuator setting is OFF. The following is true if reversing valve is disabled: If 2-pipe system is selected DO1 will activate stage 1 for heating and cooling and DO2 activates stage 2. For a 4-pipe system DO1 will control heating and DO2 the cooling device.

Reversing Valve

In binary output mode a reversing valve option is available. Select 1 if the reversing valve is to be activated while in heating mode, select 2 if the rever sing valve is active while the unit is in cooling mode.

TLC-BCR-T Engineering Manual

Remote Enable:

The unit may be remote controlled by using the external input as open contact input. Opening the binary input will force the unit into the OFF operation mode. The operation mode cannot be overridden by using the terminal or time schedules. Activating the digital input returns control of the operation mode to the terminal and time schedule.

Occupation Sensor

Remotely control comfort and economy mode for example with an occupation sensor or key switch. If the binary input is deactivated for a selectable time the un it will change to stand by mode. For a key switch, set delay time to 0.

Heat / Cool change:

Control heat and cool setting of your controller from a central location. Choose if heat or cool is to be active when contact is open.

Auto Changeover with supply media temperature sensor:

The external input may be used to automat ically determine heating or cooling mode by measuring the temperatur e of the supply media. Connect a qualified passive sensor to the external input. Heating mode is activated once th e supply temperature is above the heating limit. Cooling is activated when the supply temperature is below the cooling limit. The limits may be defined in software. Standard is 16°C (61°F) for cooling and 28°C (83°F) for heating.

Auto Changeover with outside temperature sensor:

The external input may be used to automat ically determine heating or cooling mode by measuring the outdoor temperature. Connect a qualified passive sensor to the external input. Heating mode is activated once the supply temperature is below the heating limit. Cooling is activated when the supply temperature is above the cooling limit. The limits may be defined in software. Standard is 16°C (61°F) for heating and 28°C (83°F) for cooling.

Key Card:

The external input is connected to a key card in hotels. If input is closed the unit is in normal operation with the setpoint being chosen by the end user. When input is opened, the unit will change to economy mode. A preset setpoint defined with FC12 for heating and FC13 for cooling is used instead of the selected setp oint. The setpoint shift feature is disabled.
