Sensors
Sensors incorporate fan speed control switches and are used
with CZU and IAC temperature controllers. This system is
used for the control of temperature zones in buildings, such
as hotel bedrooms or individual offices, which are air
conditioned by fan coil units.
FEATURES
• Aesthetically pleasing case designs
• Robust
• Easy to operate
• Simple wiring connections
• Simple commissioning
These sensors are specifically used for Satchwell controllers.
Models types have light that informs you that the controller
is running. All sensors use the same single gang sized case.
FEATURES
• Small physical size
• Attractive case design and neutral colour fits in with
most room designs
• Extra low voltage on all sensor types including fan
speed control versions
• Simple wiring connections
• Simple commissioning
• Controller running power light on the sensor
The DRTE Active Sensor gives proportional 0...10Vdc output
for control of rooms or small zones. The sensor will control
actuators such as Satchwell ALi and ARE. Alternately the
output can be used as a low limit on other 10 volt
equipment or as a reset signal to other controllers.
FEATURES
• Tamperproof
• Small physical size
• Reversible output ramp: heating or cooling
• Low cost installation
• Simple commissioning
Sensors incorporate fan speed control switches. These
devices are used for the control of temperature zones in
buildings, such as hotel bedrooms or individual offices,
which are air conditioned by fan coil units. Can be used with
any 0...10V actuator.
INSTALLATION DETAILS
Sensing element - Negative temp. coefficient thermistor
Switch rating - 2.5A 250Vac. Motor full load current. 12A
motor starting, 250Vac. Note: manual switches suitable for
choke controlled or capacitor controlled fan motors.
This sensor range is designed for use with controllers to
provide relative humidity measurement and temperature
control in ventilation systems.
Models are available with humidity sensing only or humidity
combined with temperature sensing. Two ranges of resistive
outputs are available across the monitored temperature
range i.e. T type or standard NTC thermistor. 2% and 1%
accuracy versions are available certified for the National
Institute of Standards Technology (NIST).
FEATURES
• Aesthetically styled, low profile packaging
• 0...10Vdc humidity output
• 24Vac or 12...24Vdc input power
• Humidity or humidity and temperature output
• Removable Humidity sensor element; replacement
elements available
• 1% and 2% versions supplied with NIST certificate
