3P-TSR Series Controller for Header Tanks

Smart Header/Break Tank Controller – TSR Series

Electronic Header Tank Controllers with Emergency Shut-off


A replacement for float switch or ball valve control allowing a header tank to be filled at high speed and vastly improved efficiency compared with twin ball-cock systems.

Pumps run with reduced temperature and runtime, reducing failures.

A reed sensor detects a low water level and activates the pump allowing it to run on for a period of time after reaching the sensor. In this way the system behaves in a manner similar to a float switch, but with far greater reliability, accuracy, and ease of construction. The problem of overlapping float switches is also eliminated.

TSR series controllers remove the need to pump through the narrow orifice of a ball-cock, giving a substantial increase in efficiency, allowing smaller header tanks to be selected, and eliminating pump failures due to persistent overheating.

Pump operation is started by the low level sensor, and keeps running after the sensor has been reached for a given time period, thus avoiding the need for the pump to start too frequently, while also ensuring there is sufficient water delivered to the header tank to meet instantaneous demands.

As a safeguard against overflow, a second sensor mounted higher on the header tank will stop pump operation if reached.

Sensors are operated at extra low voltage (12v) and low current, preventing contact burning and voltage drop issues which affect float switches.

There are no cables within the header tank, no loose floats to become jammed or entangled.

TSR Controllers also work well in conjunction with float valve mains water top-up in a hybrid configuration, allowing for mains water to be provided in the event of a power outage.

TSR Series Overview


TSR23012A operates a single sensor and output, with additional emergency shut-off sensor. For controlling either pump or mains top-up solenoid.

TSR23012DA operates twin sensors and outputs, with additional emergency shut-off sensor, and can control both a pump and solenoid together.
