network and comprises:

• Registration of messages and alarms

• Selection of operating modes and set values

• Registration and graphic representation of actual values and statuses

• Acquisition and evaluation of plant data

Technical design

Control

Compensation

Automatic sensor identification (ASD logic), including type of sensor (active or pas-sive).
Automatic activation of incorporated control functions owing to ACC logic which, through
ASD, identifies the intended purpose of the control function. This means that the control
will be optimally adapted to the plant.
P-band and integral action time (TN) are separately adjustable, so that P-control (with
integral action time = 0) or PI control can be selected.

The controller is supplied as a PI controller. The set values of heating and cooling can
be adjusted separately. Overlapping of heating/ cooling sequences is not possible.

For the control of mixed air dampers or heat recovery equipment, both operating action
and operating mode can be selected.
The actual values of the various outputs are permanently displayed.

The following compensation functions can be implemented:

• Outside temperature compensated controller set value. This function is integrated in

the controller. The parameters of compensation can be set

The output signal of the room/extract air temperature controller acts on the set value
of the supply air temperature controller. This effect (standard value is preset) can be
changed. Cascade control acquires disturbances in the supply air and offsets them
before they have an impact on the room or extract air temperature. The limitation
functions are not affected by the cascade.

For ventilating and air conditioning plants with hot water air heater batteries. Frost
protection operation is selected with DIL switch 8 (water). Frost protection is used to

• protect the air heater battery against freezing

• facilitate plant startup at low outside temperatures

All parameters for frost protection are factory-set and can be changed: Response
temperatures, set values, P-bands and integral action times. The frost protection
concept functions with both kinds of temperature acquisi tion (in the water circuit or at
the air heater battery's outlet). The protective actions are the following:

• Continuous opening of heating valve, activation of circulating pump

• Switching off the fan or closing the air damper

• Maintaining the temperature when the fan is switched off (on the water side only)

• Fault status signal in the event of risk of frost

To ensure frost protection, the use of the following sensors is required:

• QAD22.../QAE21.9 for temperature acquisition in the water circuit

• QAF63... for temperature acquisition at the battery's outlet

Control and
monitoring

The RWI65.01 provides all control and monitoring functions mentioned above.
Prerequisite:
Correct configuration of the heat source (water or electric) with DIL switch 8.

Switching on of plant,
provided:

Monitoring operation of
plants that use hot water
air heater batteries

Monitoring operation of
plants that use electric
air heater batteries

• Operating mode is set to "Automatic" ( ) and timeswitch program of timeswitch is

set to "ON", or

• Operating mode "Manual ON" ( I )

• Continuous checkback signal of plant's and circulating pump's operational status,

based on the signals delivered by the monitoring elements such as flow switch and
overcurrent protection

• Switching off actions, depending on the selected alarm priority (A or b), and operating

mode as well as delays aimed at avoiding incorrect signals are adjustable

• Permanent monitoring of frost protection

To save pump energy and to avoid damage to the pump:

• Parallel output of heating and pump on command when there is a demand for heat

• Pump kick, interval and minimum running time are adjustable

• Activation of electric air heater battery only when there is a demand for heat and

when the monitoring elements are enabled

• Continuous checkback signal of plant's operational status, especially that of the

electric air heater battery, based on the signals delivered by the monitoring elements
such as flow switch or filter switch, thermal cutout or overcurrent protection

• Switching off of plant elements, depending on the selected alarm priority (A or b)

• Adjustable alarm delays for disturbances of filter or flow

• Adjustable fan overrun times

Monitoring operation in
refrigeration plants

Efficiency supervision
of the heat recovery
system

Time switch

• Two possibilities of control
– With integrated ON/OFF command (Q20)
– With DC 0...10 V control signal via digital or binary step switches

• Adaptation to compressor or heat pump operation by setting a switching interval and

a switching differential

• Selectable pump kick for heat pump operation

• Switching off of plant elements, depending on the selected alarm priority (A or b)

An additional sensor must be installed if this function is used. Three temperature values
(temperature behind heat recovery, equipment, outdoor air and extract air temperature)
are required to calculate efficiency. The calculated value is shown on the controller and
it generates an alarm if it falls below an adjustable threshold value.
To display data points 110 to 118, set DIL switch No. 2 to the left.
The efficiency value acts as a fault indicator, for example, for defective, polluted or
incorrectly connected heat recovery equipment.
This function (display/alarming) is supported by the FLN integration solutions (AZI65.1 /
UNIGYR, VISIONIK) and LON/BACnet (AZI65.2 / DESIGO 30).
When this function is used, the Z-input is not available for other functions.

The timeswitch is a weekly time switch with programmable switching on/off times for
every weekday.
The switching on/off times can be reprogrammed at any time without having to readjust
the time of day. The switching statuses are immediately adapted to the new switching
on/off times.
Summer/wintertime changeover: Depending on the season, one hour is either added to
the actual time (display with a solid square = summertime) or subtracted from it.
The time program is stored should a power failure occur - like all other settings.

Depending on priority, fault status signals are indicated by a flashing "A" or "b" in the
display (with efficiency supervision using pointer) and by a flashing red LED located on
the acknowledge button on the unit front. At the same time, it is available as a
centralized alarm at centralized alarm output F91 (priority A) or F 92 (priority b).

Fault status signal priorities (A or b) can be selected for inputs E1 to E5, E7, E8, B9 and
Z3.

Status signal inputs E1 to E8 can be individually adapted to the contact state of the
corresponding status signal element (normally closed or normally open).

Alarm delays to avoid false alarms can be selected for status signal inputs E2 and E7.

Any fault displayed can be acknowledged from the acknowledgment button on the unit
front. When a fault is acknowledged, the priority display changes from flashing to steady
and the centralized fault status signal at centralized alarm output F … is cancelled.

The display of a priority "b" fault status signal goes out when the signal is no longer
present at the fault status signal input. When no other fault status signal is present at
the fault status signal inputs, the display in the acknowledgment button changes from
red to green.

The fault status signal indications (display and acknowledgment button) for a priority "A"
fault can be cancelled by pushing the acknowledgment button again, as long as no
other fault status signals with priority "A" are present.

The function flow diagrams at the end of this data sheet show how the fault status
signals affect the RWI65 outputs.

Mechanical design

The controller consists of controller insert and base.
The controller insert accommodates all operating elements and the electronic circuits. It
is secured to the base by two screws which are designed such that they push the insert
away from the base when they are loosened.
The microprocessor with the memory, the associated electronic components, and the
display are carried by one printed circuit board, the relays by another. Another board
serves for communication and carries a specific microprocessor with the ass ociated
interface. An EEPROM stores all setting values. In the event of a power failure, the
setting values are thus retained for an almost unlimited period of time. The reserve for
the weekly time switch (48 hours typically) is contained in the controller insert. For this
reason, the insert can be removed without having an effect on the actual time setting.
The base is made of plastic and is designed for both wall and flush panel mounting. In
the case of flush panel mounting, the controller is secured by a clamp. The base carries
four terminal blocks and a terminal strip for establishing the electrical connections with
the controller insert.

Communication cards
AZI65...

The RWI65.01 can communicate with an active bus device (master) with the aid of
– the FLN (Floor Level Network) communication card AZI65.01 or
– the LON/BACnet (Local Operating Network with BACnet protocol) communication

card AZI65.02 or

– the LPB (Local Process Bus) communication card AZI65.03
Each card contains the electronic circuits required for communication.

The compartment be-comes accessible after opening the front door and removing the
cover. The communication card slides into its compartment in grooves.

Fitting the FLN communication card in the RWI65.01 requires no re-commissioning, but
only bus registration for data exchange on the network.

Engineering notes

Installation notes

80 % of the plastics used can be recycled.
The unit uses a supercapacitor in place of NiCd batteries which need to be replaced
every two years - also for the benefit of operating safety and environmental protection.

The operating voltage required to power the controller is AC 24 V. The transformer used
must be suitable for safety extra low voltage, 100 % duty, and must have separate
windings.

Terminals Q13/Q14 and Q23/Q24 must not be used with different nominal voltages
Fuses, switches, wiring and earthing must be in compliance with local regulations.

The limitations cannot be used as safety functions. These always require separate
safety devices. All important variables that are required for commissioning are to be
shown on the plant documentation (wiring diagram, etc.), if known at the time of
planning.

The controller is designed for wall mounting (in an open space or a control panel) or
flush panel mounting (control panel front, console, etc.). The permissible ambient
conditions must be observed. First, the base is to be mounted and wired up. The cables
inside the base are to be accommodated such that the insert can be easily fitted.
Secure fixing screws only after commissioning.

Commissioning notes

Settings

Recommendation

CM2N3205E / 05.2001 Siemens Building Technologies
10/18 Landis & Staefa Divisi on

For commissioning and operation, refer to the operating instructions supplied with the
controller. When commissioning the plant, all functions of the controller and the
communications card (if fitted) are to be checked. Separate preselection of all switching
and position outputs can be made at the service level (provided operating level 3 is
active). All actual values and remote operation signals can be called up.

The controller is supplied with all control functions and parameters factory-set. Where
required, it needs to be configured for various logic functions, e.g. with electric heating,
where certain safety measures must be observed.
Changing the configuration or data settings: By means of inbuilt DIL switches.
Changing the values: With function buttons at the operating level. Any change is
immediately saved when acknowledgement is made (when the display stops flashing).

Note changed values on the reverse side of the operating instructions (folded sheet).

Legend

1) Indicates whether input E6 is high or low (time signal "yes" or "no")

2) Integral action time (TN) = 0 seconds means P-cont rol f or t he res pec t ive control sequence
Integral action time (TN) < 0 seconds means PI-c ont rol f or t he res pec t ive control sequence

3) Only if RWI65.01 has been configured for elec t ric air heat er bat t ery
On completion of the set overrun t im e, t he f ans will be switched off and the outside air dampers s hut .

4) Period of time during which the plant - after receipt of pulse at E6 - should be in operation.
When set to 0 seconds , t he plant will be switched on and off when signal is received at E6 (external
time switch) (in "Automatic" operation only and when the internal time switch has switched off or in set to
permanently OFF)

5) Period of time during which the plant may operate with 100 % recirculated air (after plant startup)

6) If operating level 1 is deactivated (data point value = 0), readjustment of values is not possible two
minutes after closing the front c over (with the exception of summer/wintertime changeover)

7) Every day at 15.00 hrs, a switch on signal of 30 seconds is f ed t o out put Q20 (periodic pum p run)

8) Only internally

9) Only internally; can be used with demonstrations when - without using an actual value filter - the control
system responds quickly to deviat ions

10) The display shows the current program number, which may vary, depending on the OEM version

11) To be set if controller is equipped with a communications card. If no comm unic at ions c ard is us ed, t he
value set has no effect on t he RWI65.01.
If the RWI65.01 is equipped with the AZI65.3 LPB communication card, the com m unic at ion addres s
becomes the LPB device number with a range of 0 to 16 and a factory setting of 0.
If the RWI65.01 is equipped with the AZI65.1 FLN communication card, the dann the valid address
range is 33 to 126.

12) Connted are the number of fan operating hours.
The readable value can be reset to zero or the former reading. To do this, proceed as f ollows:

1. Press function but t on 10 .

2. Press setting but t on "−" if c ount er s hall be reset to zero.

Press setting button "+" if counter shall be res et t o t he f orm er reading.

3. To confirm resetting: Pres s f unc t ion but t on 10 again.

13) Active only if coded for hot water heating coil!

00.00 Pump kick interval in deactivated

00.05 - 24.00 Pump kick int erval for 30 seconds at the set interval
Auto Pump will be activated f or 30 s ec onds at 24-hour int ervals, or pump runs

continuensly when the outside temperature falls befor 5 °C

Cont Pump continuensly activated

14) The value of 0 means:
Automatic activation of c as c ade aut horit y in lock ed. Maximum Economy Changeover (MECH) with pure
supply air temperature control in possible.
In that case, the connected room t em perat ure s ens or, together with the outside sensor, in only used for
MECH.

15) When using the QAF63... frost sensor, the factory-setting may not be changed!

16) The cooling signal is released above the set outside air temperature v alue. I n order t o avoid sliding on
changing outside temperatures, a hysteresis of 1 K has been integrated.
