Hurtwood manufacture a range of retrofit controls products for older and obsolete BMS’s. We have developed our flagship Satrofit IO product to provide an easy and low cost swap-out route for Satchwell BAS and Sigma systems.
A flexible and easy to service and commission system.
Aside from the retrofit applications, our IO is also a very powerful and compact product suitable for new BMS installations. Our PC-based Satrofit commissioning tool is also available that uses a direct connection via a local port on the card. This allows the IO cards and the field sensors and outputs such as actuators and variable speed drives to be commissioned by a non BMS engineer before integration into the master BMS controller, reducing installation costs and time.
Satrofit AUNC 16UI & 16UO IO cards plug directly into the BAS and Sigma UNC 696 or 796 racks and read all the pre-existing Satchwell sensors. The output cards can drive the Satchwell 8 latching relay cards.
Take a look at our video (click on YouTube logo) to see how easy it is to update your old system with the new Satrofit cards.
The Satrofit SRC-AUNC-6-6-3 controller is a direct physical replacement for the popular Satchwell IAC 420 controller. The controller has a number of pre-set control strategies for building services such as small boiler houses and fan-coil units. The selection of and set-up of these programs can be carried out through the Satrofit tool. Additional control programs for bespoke applications can be provided on request by Hurtwood.
