SER7300 and SC3000 | Fan coil terminal equipment controllers

This new cost-effective solution for upgrading line-voltage fan coil unit thermostats requires only two components: the SER7300 terminal equipment control­ler and the SC3000 relay pack. This solution allows existing line voltage wiring between the fan coil unit and temperature controller to be re-used, reducing
overall costs and installation time. The SC3000 relay pack features an onboard universal voltage power supply and line-voltage relays which directly drive
fractional horsepower fan motors and valves. This eliminates the need to install and wire costly pilot relays and transformers.

SE7300 | Fan coil room controllers

Achieve better energy efficiency and reduce operating costs with SE7300 Series room controllers. Ideal for commercial and hotel applications, these fan coil
units function with electronically commutated motors to optimise fan control sequences. With the full proportional operating of the SE7300, as opposed to
the traditional three-speed tap operation, customers will experience better control and a more comfortable environment.

24VAC - 230VAC

Occupied Mode:

Setpoints will revert to those defined by
occupied cooling and heating.

The changeover sensor will send the supply air
temperature to the controller.

Stand-by Mode (only available when PIR
motion detector cover is used):

Setpoints will revert to those defined by stand­by cooling and heating.

Unoccupied Mode:

Setpoints will revert to those defined by
unoccupied heating and cooling.

Occupied Override Mode:

The system will revert to occupied mode for
the duration determined by the “ToccTime”
parameter.

On a call for cool:

Cooling valve will modulate to maintain
room temperature. Heating valve is closed.
Dehumidification is enabled.

Dehumidification ON/OFF Sequence:

On a call for heat:

Heating valve will modulate to maintain
room temperature. Cooling valve is closed.
Dehumidification is disabled.

On a demand for dehumidification:

Dehumidification is achieved via the cooling coil
using the heating coil for reheat if necessary.

Dehumidification is only allowed in COOL mode
(or if cooling is enabled in AUTO mode).

Dehumidification is disabled if the room
temperature falls below the low ambient lockout
temperature. Which is the cooling setpoint
minus the configuration defined deadband
value.

Reheat is disabled if cooling demand reaches
100%.

Options

BACnet, Echelon and Wireless communication models available (see Appendix B for network wiring).

Remote wall mount or duct sensor ready.

Analogue outputs available (SE73xxF5045).

Can be configured for 2 pipe systems.

Binary inputs can be configured to control occupancy via door or window contact, remote night
setback or to provide alarms for service or filter monitoring.

Universal input can be configured for a changeover sensor.

Occupied Mode:

Setpoints will revert to those defined by
occupied cooling and heating.

The changeover sensor will send the supply air
temperature to the controller.

Stand-by Mode (only available when PIR
motion detector cover is used):

Setpoints will revert to those defined by stand­by cooling and heating.

Unoccupied Mode:

Setpoints will revert to those defined by
unoccupied heating and cooling.

Occupied Override Mode:

The system will revert to occupied mode for
the duration determined by the “ToccTime”
parameter.

On a call for cool:

If water temperature is less than 24°C (75°F),
valve will open to allow water flow. If supply air
temperature is greater than 25°C (77°F), valve
will close. Baseboard is always desactivated.

On a call for heat:

If water temperature is less than 24°C (75°F),
valve will close and the duct heater will be
activated. If water temperature is greater than
25°C (77°F), valve will open to allow water flow.
If the water flow is unable to satisfy the demand,
the baseboard is activated.

Options

BACnet, Echelon and Wireless models available (see Appendix B for network wiring).

Analogue 0-10 VDC outputs available (SE73xxF5045).

Remote wall mount or duct sensor ready.

Can be configured for 4 pipe systems.

Can be configured to single or two speed fan.

Binary inputs can be configured to control occupancy via door or window contact, remote night
setback or to provide alarms for service or filter monitoring.

On a call for heat:

Dehumidification is disabled.

ON/OFF Sequence:

On a demand for dehumidification:

Dehumidification is achieved via the cooling coil
using the heating coil for reheat if necessary.

Dehumidification is only allowed in COOL mode
(or if cooling is enabled in AUTO mode).

Dehumidification is disabled if the room
temperature falls below the low ambient lockout
temperature. Which is the cooling setpoint
minus the configuration defined deadband value.

Reheat is disabled if PI cooling demand
reaches 100%.

Options

BACnet, Echelon and Wireless communication models available (see Appendix B for network wiring).

Remote wall mount or duct sensor ready.

Can be configured for 2 pipe systems.

Binary inputs can be configured to control occupancy via door or window contact, remote night
setback or to provide alarms for service or filter monitoring.

Universal input can be configured for a changeover sensor.
