Control Options

Bypass Options:

• The standard external bypass uses a thermostatically-controlled valve to adjust bypass flow and achieve cold-water protection
• All units available without an external bypass; cold-water protection provided in the field
• The Cold Water Run (CWR) option provides electronic control of a variable-speed pump to continuously adjust bypass flow, achieving realtime cold-water protection

Cold Water Start

Cold Water Run

 

For the same reason stated for Cold Water Starts, it is even more important to provide protection against condensation from cold inlet water on systems where the return water temperature to the boiler will always be below the acceptable minimum. Raypak’s Cold Water Run system utilizes a variable-speed pump to inject just the right amount of water from the main system loop into the boiler to maintain the optimum inlet temperature. This approach allows the full capacity of the boiler to be utilized to meet the system load, while at the same time continuously maintaining the optimum inlet water temperature to prevent condensation.

 

On-Board Diagnostic Center

Raypak's Hi Delta (302B thru 2342B) comes equipped with a microprocessor-controlled diagnostic control center that displays its information on a 2x20 character LCD display in plain English. This control monitors ystem safeties, ignition faults and sytem status, while storing up to 16 reported faults. Raypaks diagnostic center also monitors the fault outputs of the Fenwal ignition control. The Fenwal's flash codes are converted into real English fault codes that anyone can understand. The control is also equipped with a SPDT dry contact relay output that is switched anytime a safety fault occurs. This can be used for a heater alarm or a BMS safety interface.

1. Lightweight Refractory Panels

Multi-peice ceramic fiber panels enhance combustion while minimizing heat retention

 

2. Fully-enclosed Headers

Temperature sensors and lead wires/capillaries are protected from weather, vandalism, and accidental damage during installation and service

 

3. Flue Connection

Top or back outlet flue connections offer greater installation flexibility

 

4. Air Filter

An easily-cleaned combustion air filter protects the burners from airborne particles including flying insects.

 

5. On-Board Diagnostic Center

Factory mounted standard equipment (302 - 2342). Gives relevant service feedback as well as possible solutions to clear the fault. All in plain English, no cryptic codes to decipher. The control stores up to 16 fault codes in its history file for the service technician to review.

 

6. Status Display Lights

Up to 12 high-density LED lights, visible up-front, indicate the operating status of the boiler.

 

7. Construction

The cabinet and all internal parts are made from galvanized, aluminized or stainless steel. The exterior is protected by textured powder-coat paint, ideally designed for indoor or outdoor installations.

 

8. Central Point Wiring

Factory-made wire harnesses connect all electrical components to an easy-to-troubleshoot circuit board with multi-pin connectors.

 

9. Heat Exchanger Tubes

Time-proven copper finned tubes and optional cupro-nickel tubes stand up to even the harshest water conditions.

 

10. Burners

Special stainless steel alloy pre-mixed burners provide clean, robust combustion and meet all low NOx regulations.

 

11. HSI Access Panel

A small panel provides access to both the hot surface igniter and the flame sensor to aid inspection and service
