Georg Fischer Signet proudly announces the introduction of the 8900 Multi-Parameter, Multi-Channel, 
Multi-Language Controller now with a BTU calculator. It is important to note that there is no increase in 
price for this added feature.This new BTU feature is designed to measure the energy and power con-
sumption in a heat transfer sytem. Any of the following calculations can be done simultaneously: 
one heating and one cooling, two heating or two cooling. Programmable density and heat capacity para-
meters are offered to increase the measurement’s accuracy.

This added capability enables the 8900 Multi-Parameter to suit an even longer list of applications.

menu display system in English, French, German, Spanish, Italian and Portuguese. Now with the BTU 
calculator, the 8900 Multi-Parameter boasts added benefits: 
• Executes 2 simultaneous BTU calculations

Production and availability are effective immediately and the serial number to the first 8900 unit shipped 
with BTU will be posted on the web site for reference. Customers can return their current units for re-flashing 
(free of charge), but customers are responsible for freight charges in shipping the unit to the factory. The 
turn-around time is approximately 5 business days, but can be expedited at the customer’s request.
