Greystone Energy Systems GWTR24 Series Quick Start Manual

WIRELESS ROOM TRANSMITTER
GWTR24 SERIES
PRODUCT DESCRIPTION
The GWTR24 externally powered wireless
transmitters are for detecting indoor
temperature, humidity and CO2 level. The
transmitters can also be equipped with a
display, advanced setpoint knob, and
occupancy detection. The transmitters require
24 V supply voltage. Transmitters are
compatible with the Greystone MESH wireless
network.
The information is transmitted to the base
unit (GWBU) according to the base unit poll
interval. Data may be additionally transmitted
using change-of value (COV) based
transmission. COV means that the data is sent
to base station after the
value has changed enough. If COV based
transmission is used, the required value
change must be configured with the
Greystone ConfigTool app.
The wireless network needs one base
unit. Commissioning is done by using
the Greystone ConfigTool smart phone
application.
Greystone Energy Systems, Inc. reserves the right to make design
modifications without prior notice.
