SEQUENCE OF OPERATION

Some electric utility companies will offer discounts for using electricity during “Off Peak” Times of the day. The system allows the use of an “Off Peak” meter, which interrupts power to the lower element during high power demand periods.

Sequence of Operation- Double Element, Non-Simultaneous Operation, Single Phase, Off Peak.

1Line voltage is applied across terminals

L1 & L3 of the upper thermostat. Line voltage from off peak meter is supplied to terminal L1 of lower thermostat. ECO in the upper thermostat is closed, so there is voltage at terminal L4 of upper thermostat and to one side of the upper element.

Tank is cold therefore both thermostats

2are closed at terminal T2 (calling for heat). The circuit is complete through the upper thermostat only, allowing current to flow through upper element.

3When upper thermostat is satisfied, it opens at terminal T2 interrupting current flow through upper element, and closes at terminal T4 allowing voltage to pass to one side of the lower element. This completes the circuit through the lower thermostat and off peak meter allowing current flow through lower element.

4When the lower thermostat is satisfied, it opens at terminal T2 interrupting current flow through lower element. The system is now in stand-by mode waiting for the next call for heat

5During peak power demand periods as determined by the local utility, the off peak meter will interrupt power to terminal L1 of lower thermostat. Only the top thermostat/element combination is allowed to operate during this period.

Bradford-White Corp M-2-50T6DS service manual From Off Peak Meter

M-2-50T6DS specifications

Bradford-White Corp is renowned for its commitment to quality and innovation in water heating solutions, and the M-2-50T6DS model exemplifies this philosophy. Designed to meet the needs of both residential and light commercial applications, this 50-gallon gas water heater is engineered for efficiency, reliability, and ease of use.

One of the standout features of the M-2-50T6DS is its high recovery rate, which is achieved through a powerful atmospheric vent design that allows for quick heating of water. The heater’s 40,000 BTU per hour input ensures that there is always a sufficient supply of hot water available when needed. This makes the unit ideal for households with multiple bathrooms or for commercial settings where high hot water demand is common.

The Bradford-White M-2-50T6DS incorporates a state-of-the-art ignition system known as the Direct Spark Ignition (DSI). This technology provides a reliable start-up with minimal energy consumption, enhancing both safety and efficiency. The DSI system reduces the risk of pilot light outages and simplifies the ignition process, making it user-friendly.

In terms of construction, the M-2-50T6DS is built with a robust design featuring a glass-lined tank for superior corrosion resistance. This durable tank is insulated with CFC-free foam, ensuring optimal heat retention and minimizing energy loss. Coupled with the unit's Energy Factor rating, it reflects Bradford-White's dedication to energy efficiency, offering long-term savings on utility bills.

Another notable characteristic is the heater's integrated thermal expansion tank, which helps manage water pressure and reduces damage to your plumbing system, thereby enhancing the overall longevity of both the heater and your home’s plumbing infrastructure.

Safety is a priority with the M-2-50T6DS as well. The model is equipped with a dual-sensor thermostat that monitors the temperature and adjusts accordingly to prevent overheating. Additionally, it features a temperature and pressure relief valve for added safety, ensuring that the unit operates within safe parameters.

In summary, the Bradford-White M-2-50T6DS water heater epitomizes advanced engineering and high performance. With a focus on efficiency, reliability, and safety, this model is an excellent choice for anyone in need of a dependable source of hot water, demonstrating Bradford-White's unwavering commitment to quality in the water heating industry.
