Avv, And Avr - Daikin AVS Installation Manual

15 Room Temperature Sensor - (S1) The unit mounted sensor is
located in the sampling chamber (front, center section) where
room air is continuously drawn through for prompt response
to temperature changes in the room. A Remote Wall Mounted
Temperature Sensor is also available for remote room temperature
sensing. (optional accessory).
16 Discharge Air Temperature Sensor - (S2) The sensor is
located on the second fan from the right to sense discharge air
temperatures.
17 Outdoor Air Temperature Sensor - (S3) The sensor is located in
the outdoor air section of the unit before the outdoor air damper.
With network applications, the unit mounted sensor can be
overridden by a remote sensor through the network.
18 Outdoor Air Humidity Sensor (S8) (optional) - Unit mounted
humidity sensor for units using Expanded outdoor enthalpy
economizer or Leading Edge indoor/outdoor, true enthalpy
comparison economizer. The sensor is located in the outdoor air
section of the unit before the outdoor air damper. With network
applications, the unit mounted sensor can be overridden by a
remote sensor through the network.
19 Room Humidity Sensor (S6) (optional) - Unit mounted humidity
sensor for units capable of passive or active dehumidification
or with units using Leading Edge indoor/outdoor, true enthalpy
comparison economizer. The sensor is located in the sampling
chamber (front, center panel) where room air is continuously drawn
through for fast response to humidity changes in the room. With
network applications, the unit mounted sensor can be overridden
by a remote sensor through the network.

Plug-in Control Module
20 CO Sensor (S7) (optional) – Unit mounted, single beam absorption
2
infrared gas sensor with a sensing range of 0 – 2000 ppm and
voltage output of 0 to 10 VDC (100 ohm output impedance).
The Pitot Tube sensing device is located in the unit ventilator's
return air stream. The optional CO
Demand Control Ventilation feature to vary the amount of outside
air based on actual room occupancy. With network applications,
the unit mounted sensor can be overridden by a remote sensor
through the network.
21 Control Valve(s) (not shown) – Optional accessory valve(s) may
be either 2 position "End of Cycle" (AVS models) or modulating
(AVV and AVR models), to control the quantity of water through
the coil. A vailable in 2-way or 3-way configurations. Spring return
actuators are required for all hot water and steam heating valves.
All heating valves are Normally Open (NO) and all cooling valves
Normally Closed (NC). (See piping/valve section)
22 Water In Temperature Sensor (S5)(not shown) – The water
in temperature sensor is factory wired on 2-pipe CW/HW units
only. The sensor must be field installed and insulated (by others)
on the supply connection of the hydronic coil. The sensor must be
located on the supply connection where there is continuous water
flow. It is located on the same side as the coil connections. The
sensor measures the entering water temperature to determine if
the temperature is acceptable for either heating or cooling based
on the unit's operating state. (see piping section)
