Use The Economizer Controller works in combination with a range of sensors, damper actuators,
thermostat, fans and compressors to make use of unconditioned outside air to cool a
building and improve inside air quality.
Features
●Flexible sensor inputs accept Type II NTC 10K or 0-10 Vdc standard sensors, or
Siemens QFM2160U or QFR9530 combination temperature/humidity sensor for enthalpy
control
●Can be used with Siemens OpenAir® damper actuator GQD, GMA or GCA series
●24Vac digital inputs for indication of occupancy, 3-stage Cooling Stage input, Shutdown,
Heat Conventional, Heat Pump Changeover (HP(B)/HP(O)) or Preoccupancy
●24Vac relay outputs (digital) for 3-stage Cooling Stage output, Exhaust Fan, VFD On/Off
(Variable Speed Supply Fan Enable), System Alarm output (Title 24) or Energy
Recovery Ventilation (ERV)
●Anti-freeze protection
●Fault detection and alarming
●Brownout protection
Technical Design The Economizer Controller has 7 analog inputs, 2 analog outputs, 5 digital inputs, 4 digital
outputs, an RS485 port and a USB host interface. POL224.00 is additionally equipped with a
housing (front and rear, snap-on design), three LEDs, three operation buttons and inbuilt

NOTICE
If different faulty events occur at the same time, sensor/DAC LED lights up following the
priority below: Red (Fast Blinking) -> Red (On, Steady) -> Red (Blinking) -> Yellow -> Off ->
Green. For example, if there is a humidity sensor error and air temperature failure at the
same time, the sensor LED turns red rather than yellow.
After the Economizer controller enters the running state, it may take one minute for
peripheral devices to complete initialization. Before that, LED indication might be unstable.

Notes
Security
CAUTION
National safety regulations
Failure to comply with national safety regulations may result in personal injury and property
damage.
●Observe national provisions and comply with the appropriate safety regulations.
Mounting The Economizer Controller can be mounted to sheet metal ductwork. When mounting, note
the following:
●Mount the controller in a position that allows clearance for wiring, servicing, and removal.
See Mounting Instructions for required mounting clearances.
●(For POL224.05) four spacers (M3.5 x L (L ≥10 mm) ) and four M3.5 screws are
required. Metal spacers are recommended.
●(For POL224.00) two No. 6 3/4” self-tapping screws are required.
●Siemens does not provide screws or spacers with the product. They must be obtained
separately.

Wiring Use only class 2 rated power source with proper current limiting.
●Use only class 2 rated power source with proper current limiting.
●Disconnect power supply before beginning wiring, or making wiring connections, to
prevent electrical shock or equipment damage.
Commissioning Commissioning configures I/Os and tests the damper operation and any configured outputs.
It can only be done using the Climatix Mobile application or under Configuration State from
the controller. The three LEDs blink yellow if the controller enters Configuration State.
To Commission under the controller’s Configuration State
a)From the default HMI screen, press Enter + Up.
The '5CONFIG STATE' screen displays.
b)Press Enter, and then confirm the switch by pressing Enter again.
c) Configure I/Os and/or test connected devices.
d)If configurations are done, press Enter + Up or Down to switch to the '8RUN STATE'
screen, then press Enter twice to go back to Running State.
The '1FREECOOL' screen displays.
Commissioning is also possible from the mobile application. See Product Documentation
[▶6] for more information.
Don't interrupt damper test once it starts.
Operation Customers can download the mobile application by scanning the Mobile APP QR code on
the device and perform operations on their smartphones or tablets or directly on the device.
When performing operations from the mobile application, ensure that a WLAN stick is
plugged into the USB port and connection between the smartphone/tablet and the WLAN
network is established.
Operations that can be performed from the local device are as follows:
●Change basic settings like the following:
–Temperature shutoff setpoint
–Enthalpy shutoff setpoint if an RH input is detected
–Mixed-air temperature modulating setpoint
–The ppm value for DCV (Demand Control Ventilation)
–Damper minimum position
–Temperature unit
–Fan airflow or CFM value
–ERV (Energy Recovery Ventilation) outside air temperature setpoint if 'ERV' is
selected for AUX1-O or AUX2-O
–Exhaust fan startup setpoint if exhaust fan is chosen
–Etc.
●Change advanced settings like the following:
–Damper position anti-freeze protection settings
–Damper position during shutdown
–Highest stage cooling delay time
–Min. and max. leaving air temperature

This equipment has been tested and found to comply with the limits for a Class B digital
device, pursuant to part 15 of the FCC Rules. These limits are designed to provide
reasonable protection against harmful interference in a residential installation. This
equipment generates, uses and can radiate radio frequency energy and, if not installed and
used in accordance with the instructions, may cause harmful interference to radio
communications. However, there is no guarantee that interference will not occur in a
particular installation. If this equipment does cause harmful interference to radio or television
reception, which can be determined by turning the equipment off and on, the user is
encouraged to try to correct the interference by one or more of the following measures:
●Reorient or relocate the receiving antenna.
●Increase the separation between the equipment and receiver.
●Connect the equipment into an outlet on a circuit different from that to which the receiver
is connected.
●Consult the dealer or an experienced radio/TV technician for help.
This device complies with Part 15 of the FCC rules. Operation is subject to the following two
conditions:
1. This device may not cause harmful interference, and
2. this device must accept any interference received, including interference that may cause
undesired operation
