Side Panel
Lockable main panel disconnect allows for secure shut down of panel during installation or service.
Grill protects cooling fan from objects entering blades.
Cooling fan ensures good air flow through panel to keep components within proper operating temperatures.
User Interface
Panel door mounted user interface allows access of boiler/zone information such as operating temperatures, set-point temperatures and operating statuses.
Password-protected installer set-up menu allows for protection of important settings.
Backlit display allows for use within dimly lit boiler rooms or installation areas.
DHW Set-Point Control
Door-mounted set-point control in conjunction with Disable/Enable switch and pump Auto/Off/On switch.
Set-point display indicates actual temperature output.
The Auto/Off/On switch allows for pump control from either the set point control or manual operation.
Pump Control
Proper pump control with door-mounted Auto/Off/On switch. Switch illuminated to indicate operation.
The red Fault indicator above switch, allows user to be aware of problem with pump output control. Optional audible alarm or remote notification possible too.
Door Locks
The panel door locks discourage unwanted entry into panel. A key is required to open panel door to reveal components within.
Incoming Power Status
Lights on front of panel indicate operating status of incoming power supply.
Device Fuse Block
Proper protection of all output devices requires that fuses are used for each phase.
The fuse holder is designed to allow for easy replacement by tilting holder forward. For two phase and three phase output devices, the entire block is tilted.
Smaller amperage devices require simple glass style fuses. The fuse holder for these allow viewing fuse filament without removing fuse entirely. Once again, replacement is simplified by pulling holder forward.
Sensor and Low V Terminals
Connection of control sensors, as well as "lower" voltage connections, are provided at the top of the panel.
All terminals are logically numbered to allow for easy termination to field wiring. Generally, the terminals are smaller than that of high voltage devices because of the type of wire used for the devices.
Transformers
Including a transformer in a control panel is very common. Step-down transformers such as a 120VAC to 24VAC allow for operation of low voltage devices such as 24V mixing valves, isolation valves or zone valves.
Relays
These are devices which allow you to control a larger Voltage/Current with a lesser voltage.
Relays are available in a multitude of contact configurations, voltage and current ratings.
PLC
A programmable logic control can be programmed to meet the operational requirements for our customers. A PLC can be programmed to rotate pumps or boilers, based on timers, external inputs or any input signal.
Mixing Valve Zone Control
The mixing valve zone control can be used to operate a mixing valve for radiant floors, panel rads, baseboard or even high temperature fan coils.
The functionality is based on outdoor reset logic. This basically means, as it gets colder outside, the valve provides more heat through modulation of the valve.
Motor Circuit Controller
These are pump controls that are generally used on 3-phase pumps. It is designed to trip in the event of a short circuit as well as offering thermal overload protection.
If it senses either one of these conditions, the device will trip and thereby shut the pump down.
When used in conjunction with an auxiliary contact, a failure indicator will become illuminated on the front of the panel.
Contactor or Motor Starter
This device performs the actual switching of the pump. Similar to a relay in operation, the contacts are designed to handle greater amperage/ horsepower loads.
Certification Sticker and Seal
Each and every panel receives a CSA sticker to show the panel is certified by KWE. The sticker displays important information about the panel as to Voltage and Current requirements.
Foam seal around perimetre of door protects from potential water entry when closed and locked.
Door Lock
Strong latch provides a securely closed door as well as a proper seal.
Quarter turn with key to open door.
Set-Point Control
Backside of set-point control device switch block for Auto/Off/On and Disable/Enable switch.
Main Panel Disconnect and Fan
Backside view of disconnect switch.
Ball bearing fan provides quiet operation while keeping panel cool.
Distribution Blocks
To facilitate distributing power throughout the panel, a distribution block is used. Enables a multitude of loads, within the panel, to be easily terminated.
Pump Control
Switch blocks and fault indication for pump control output.
Tool-less mounting latch allows for easy removal of contact and lamp block.
Replacement of switch block just as easy with snap-on switch block fasteners.
Optional LED indicators for fault and operation status allow for long service life.
Fuse Rating Sticker
Convenient sticker inside of panel lists fuse rating and location. Provides valuable information of replacement of fuses.
Incoming Line Voltage Terminals
Properly sized line voltage terminals are provided for connection ease.
Terminals are numbered for ease of reference to supplied schematic that is shipped with every panel.
Fuses
Main fuses provide protection required for panel.
