II. TEMPERATURE CONTROLLER

The Temperature Controller is used to set and control the oven temperature. Depending on the oven, model, the con- troller has several functions:

•On gas ovens with On-Off gas valve operation, the tem- perature controller opens and closes the high flame solenoid. This allows 100% or 0% gas flow to the burner in response for the need for heat to maintain the set point temperature. The temperature controller has no effect on the low flame bypass or oven ignition.

For this operating mode, the temperature controller is set to the On-Off Mode as described in the Kit instructions.

•On gas ovens with modulated gas valve (PID) opera- tion, the temperature controller sends a signal to the amplifier board which in turn controls the operation of the modulating valve. This allows a modulated gas flow of any necessary value from 0-100% in response for the need for heat to maintain the set point. The tem- perature controller has no effect on oven ignition.

For this operating mode, the temperature controller is set to the PID Mode as described in the Kit instructions.

•On electric ovens with On-Off heater activation (includ- ing most PS200-series and PS360-series electric ov- ens), the temperature controller permits or cuts power to the heating elements as necessary to maintain the set point temperature.

For this operating mode, the temperature controller is set to the On-Off Mode as described in the Kit instructions.

On electric ovens with variable pulse heater activation (including PS555 electric ovens), the temperature con- troller sends its signal to a controller module that con- tains an amplifier board and two solid state relays. The relays activate the heating elements at 100% power on a fixed cycle time, for a length of time proportional to the signal from the temperature controller.

For this operating mode, the temperature controller is set to the PID Mode as described in the Kit instructions.

Note that temperature controller P/N 46837 (inc. with Service Kit 47321) includes a dedi- cated variable pulse mode intended for the PS536 electric oven. This special mode is NOT used on the PS555.

The temperature controller regulates the cooldown func- tion. NOTE: PS200VL-series ovens do not include a cooldown function.

On most PS200-series and PS300-series gas ovens (except the PS200VL), the temperature controller moni- tors the high limit. All other oven models use a High Limit Control Module that is independent of the tem- perature controller.

The Middleby Marshall PS555 is a standout commercial pizza oven renowned for its performance, efficiency, and advanced technologies. Designed with the modern pizzeria in mind, the PS555 delivers exceptional cooking results while maximizing energy efficiency and throughput.

One of the key features of the PS555 is its innovative cooking technology, which incorporates both convection and radiant heat. This unique combination ensures that pizzas are cooked evenly and quickly, achieving a perfectly crispy crust and evenly melted cheese every time. The oven’s high-speed air impingement system accelerates cooking times, allowing pizzerias to serve more customers in less time without compromising quality.

The PS555 is designed with a spacious cooking chamber that can accommodate multiple pizzas simultaneously. With its ability to fit pizzas up to 18 inches in diameter, the oven is ideal for establishments with high demand. Additionally, the adjustable conveyor speed allows operators to customize the cooking time based on their specific menu items, enhancing versatility and productivity.

Energy efficiency is a hallmark of the Middleby Marshall PS555. The oven utilizes advanced insulation materials to minimize heat loss, ensuring that it operates at optimal temperatures while consuming less energy. This efficiency not only reduces operating costs but also contributes to a more sustainable kitchen environment.

User-friendly controls make it simple for operators to manage the cooking process. The PS555 features digital controls with programmable settings, enabling quick adjustments to temperature and cooking time. This ensures consistent quality across different shifts and helps maintain product standards while simplifying staff training.

Durability is another defining characteristic of the PS555. Built with high-quality materials, the oven is designed for heavy use in busy commercial kitchens. Its stainless steel construction ensures resistance to wear and tear, making it a worthwhile investment for any pizzeria.

In summary, the Middleby Marshall PS555 pizza oven is a high-performance piece of equipment that combines advanced cooking technologies, efficiency, and durability. Its ability to deliver consistently excellent results while streamlining operations makes it an essential asset for any pizza business aiming to enhance its productivity and customer satisfaction.
