INTRODUCTION
Note to Reader: This manual is to be used as an aid to assist in the commissioning of the SYX660, SYX661, SYX662,
SYX663 and SYX664 Controllers from SyxthSense. The SYX66x range of controllers have identical functionality
apart from the sensor types they work with. For the purposes of efficiency this one guide reflect all the above
controller types and to help reduce repetition the controller is hereon referred to as SYX66x.
The SYX66x is a simple controller which is designed to suit the control needs of
today’s smaller commercial and larger
domestic properties. It can be configured control one, two or multiple boilers (via 0-10v sequencer), or provide burner
modulation. Valve and/or Boilers can be compensated. Plant control options are with optimum start/stop, direct boiler,
direct valve or boiler and valve compensation. The heating circuit is easily configured for constant temperature as
required by adjustment of the heating curve.
A separate timed output channel is provided for the provision of hot water, the HWS relay option is required for this
output. The HWS control routines can be used independently or combined with the boilers. If combined with the boilers
then the option of boiler heat demand by the Hot Water is provided by an optional auxiliary digital input, this increases
energy savings.
Fast installation and operation are key features of the SYX66x. The controller has a base application that is adjusted
during the commissioning phase by simple parameter choices. The use of practical default settings means that the
system is ready to control a radiator system with minimal adjustments. Additional self-adapting features adjust the
control settings to the buildings performance.
An override menu (Panel Switch) allows you to override the control mode without the need to change any settings. If set
point and time settings of the unit is required these can be made using either the inbuilt display, optional remote
colour touchscreen, or the in-built web browser that is compatible with any Laptop or Smart Device.
The info button provides direct access to visual indication of all input and output status.
The Malfunction button allows the alarms to be seen and actioned
There is a user button to quickly acknowledge and clear Alarms
The simple user screen is text based using simple language and is backlit for easy use in poor plant room lighting.
The internal web browser allows local site and remote site monitoring/supervision. Users can interrogate relevant
parameters with 3 distinct user levels. Access levels are changed by entering the correct code between: Information
Level (default), Change Level, Set-up level.
Historical records of temperature are taken at regular intervals and sensor are monitored for their operational
condition. Performance can be assessed and savings increased through better information and analysis. Simple
configuration and simple use are key features of the SYX66x.
