some control options

We can control standard and EC fan types. Standard fans can have an added speed control; both single phase and three phase fans, options are electronic, transformer or inverter speed controls. The speed setting can be inside the panel for commissioning only, on the panel front or remote giving the user easier access to the controls. The fan speed can also be linked to temperature or pressure in the system to retain a constant pressure.

We can control various types of heating, Electric (staged or thyristor) Hotwater (LPHW), Gas burner and Heat Pump. Electric heating control and Gas burner control include interlocks with the supply fan controls and also include a fan run on timer to ensure the heat is dissipated. The LPHW control includes a frost thermos stat to protect the coil from freezing, this also locks off the supply fan to ensure cold air is not supplied to the coil in a frost condition. The Heat pump control includes a airflow proving switch to ensure there is airflow present before the heat pump can run.

We can control various types of cooling control, these include a cooling coil, heat pump and dx cooling. The  cooling is interlocked with the heating coil so they cannot be on together this includes a dead band. The heat pump can be a single stage or multiple stages, it can be volt free enable or 0-10v controlled depending the heat pump being installed. Dx cooling is usually done as a volt free signal, this can also be multiple stages. 

We can control Bypass, Mixing Box, Inlet and Exhaust dampers. Dampers can be 230v or 24v (we can supply with the panel). Bypass damper includes a n internal thermostat controller and duct sensor, the duct sensor monitors the fresh air. The mixing box damper control will monitor the fresh air and extract air to determine the level of fresh air to bring into the system. Inlet and Exhaust dampers are interlocked with the corresponding fans, the fans can only run once the dampers are open, the damper close when the fans are not required to run. 

We can control the thermal wheel, this can be just an enable signal or a 0-10v control signal. The wheel is controlled by a sensor in the exhaust air.

We can monitor filters using differential pressure switches (we can supply), when the filter become dirty a lamp on the panel door will illuminate to show that the filter needs to be either cleaned or replaced. We can include a volt free output so this can also be monitored remotely.

We can include a 7 day time clock into the system, this can be inside the panel, on the panel door or remotely. The panel will include Hand and Auto buttons on the panel. In Auto mode the system is controlled by the time clock. In Hand mode the panel will run 24/7 and ignore the time clock, the Hand button overrides the Auto button. With both Hand and Auto off the panel will be off. If BMS contacts are included the panel will only run in auto mode when the time clock is in active mode and the BMS contacts are closed.

We can include links to a BMS enable signal. The panel will include Hand and Auto buttons on the panel. In Auto mode the system is controlled by the BMS enable signal (close to enable). In Hand mode the panel will run 24/7 and ignore the BMS signal, the Hand button overrides the Auto button. With both Hand and Auto off the panel will be off. If a time clock is included the panel will only run in auto mode when the time clock is in active mode and the BMS contacts are closed.

All Panel72 panels have fire alarm contacts, these are 24v contacts normally closed open on alarm. When the contacts are open the whole system will shut down (unless we are controlling a smoke damper system). 

All Panel72 panels have a 24v control circuit (unless otherwise specified), The cables are fitted with number identifications and ferrule fitted to each cable end.
