Specialists in intelligent sensor technologies

C Squared - BACnet sensors and controllers

Our sister company C Squared (C²) specialises in the manufacture and supply of intelligent room sensors for the HVAC market, designed by our in-house controls engineers. C Squared has developed the iSC™ range of intelligent temperature, humidity and CO₂ sensors - the latest concept in intelligent sensor technology. Specifically designed to meet the HVAC control requirements of modern building systems which communicate using the open source BACnet protocol.

With the BACnet versions you can write the control algorithms yourself or ask us to supply a complete Building Management System (BMS). Visit: www.csquared.co.uk

Installing yourself, need replacements? Obsolete actuator?

We can supply all control manufacturers equipment, along with our own brand gas safety panels, thermal links, gas solenoid valves, and knock-off buttons. We can also supply replacement actuators for the vast majority of obsolete 2/3 port valves, just email the original valve reference/voltage required or a photograph and we will come back to you. We can also offer alternative products for the obsolete replacement market. Our range of pre-configured controllers will replace your obsolete kit - you can even reuse the sensors/valve actuators.

Stand Alone Controls

A choice of controllers suited to simple applications or more complex control schemes. All controllers can be stand-alone or used as part of a network. Typical controller configurations include control of:- boilers, pumps, AHUs, solar panels, photovoltaic cells, heat pumps

Optimiser/Compensator

A range of versatile, multiple function controllers providing optimum start/stop; outside air compensated flow control of a mixing valve or direct with the heating boilers; boiler sequence control of up to two boilers; Domestic Hot Water Service (DHWS) either combined with the heating boilers or separate.

An extensive range of control products is also available to compliment the range.
Sensors - for temperature, humidity, velocity, pressure.
Actuators - for linear and rotary control of valves and dampers.
Gas safety solenoid valves - up to 150mm as standard, TL72 thermal links.
2, 3 and 4 - port valves - for water and steam applications, from small zone valves to large central plant schemes.

Values and Actuators

The most important part of a control system is the motorised valve, if incorrectly sized the system will not control correctly - we offer a free valve motorised valves sizing service.

Our range of valves and actuators includes:

On/off or 0/10V actuators
Boiler isolation butterfly valves
Rotary shoe valves and actuators
Lift or lay valves and actuators
