It might be the white wire has been moved from its original location next to the YL wire to one of the scratched out PCB solder points on the right side of the board. This may have been done to bypass the low limit/circ control.

It’s also possible that the black jumper wire was added to bypass the hot side of the transformer and keep the connection from the hot L1 through the jumper on the front S1 to S2 and down to the RD.

It’s important to note that making modifications to the aquastat circuit board can be dangerous and should only be done by a qualified technician. If you are not familiar with electrical circuits and wiring, it is recommended that you seek the assistance of a professional to help you understand the changes that have been made and to determine if they are safe.

How does a triple aquastat work?

A triple aquastat is a type of temperature control device used in boilers and heating systems to regulate and maintain the temperature of the water. It is called a “triple” aquastat because it has three separate temperature sensors and controls.

Components of Triple Aquastat

The main components of a triple aquastat include a temperature sensing bulb, a control switch, and electrical wiring. The temperature sensing bulb is filled with a heat-sensitive liquid and is connected to the control switch by a tube. As the temperature of the water changes, the liquid in the bulb expands or contracts, causing pressure changes that activate the switch.

Operation of Triple Aquastat

The triple aquastat works by constantly monitoring the temperature of the water in the heating system and controlling the boiler accordingly. There are three separate temperature sensors and controls, each with its own set point, that work together to maintain the desired temperature range.

The first control is the low limit control, which turns the boiler off if the water temperature drops below a certain point. The second control is the high limit control, which turns the boiler off if the water temperature exceeds a certain point. The third control is the circulation control, which ensures that the water is circulating properly through the system.

Advantages of Triple Aquastat

The main advantage of a triple aquastat is its ability to provide precise temperature control and to ensure safe and efficient operation of the heating system. The multiple temperature sensors and controls allow for a wider range of temperature control, reducing the risk of overheating or underheating and preventing damage to the system.

A triple aquastat is a useful and important device in boilers and heating systems, providing precise temperature control and ensuring safe and efficient operation. By constantly monitoring the temperature of the water and controlling the boiler, the triple aquastat helps to maintain a stable and comfortable temperature, and prevent damage to the system.
