Automatic sensor identification (ASD logic), including type of sensor (active or passive).
Automatic activation of optimum controller configuration through ACC logic which, via
ASC, identifies the intended use of the control function. As a result, the control is
optimally matched to the plant. P-band and integral action time (TN) are separately
adjustable so that P-control (with integral action time TN = 0) or PI control can be
selected.
The controller is supplied as a PI controller. The setpoints of both heating and cooling
can be adjusted separately. Overlapping of heating/cooling sequences is not possible.
For controlling mixed air dampers or HR equipment, both the operating action and the
operating mode can be selected.

• Room-supply air temperature or extract air-supply air temperature cascade control.
Connection of the room or extract air temperature sensors (terminal B1) and supply
air temperature sensors (terminal B2) automatically activates cascade control. With
cascade control, the room or extract air temperature is maintained at a constant level.
The room or extract air temperature represents the controlled variable whose setpoint
can be read and adjusted on the controller’s second operating level. The supply air
temperature is shifted in dependence of the deviation of the room/extract air
temperature from the setpoint of room/extract air temperature. The extent of setpoint
shift is calculated via cascade authority (adjustable from 0 to 20).
– Room supply air temperature or extract air supply air temperature cascade control
with fixed supply air limitations (mode of control 1).
If the supply air temperature drops below the limit set on the controller, the
integrated minimum limitation takes over control and prevents the supply air
temperature from dropping farther.
The set limit is maintained at a constant level. The same considerations apply to
maximum limitation.
– Room-supply air temperature or extract air supply air temperature cascade control
with shifting supply air limitations (displacement ventilation) (mode of control 2).
The shifting limits of the supply air temperature are calculated in dependence of the
actual room or extract air temperature, whereby the supply air temperature must
remain within the boundaries dictated by the selected values of minimum and
maximum limitation.
• Supply air temperature control (mode of control 3).
If a supply air temperature sensor (terminal B2) is connected, supply air temperature
control is automatically activated. With this mode of control, the supply air
temperature is maintained at a constant level.
The required mode of control can be selected.
The RWI65.02 is a sequence controller with three modulating outputs (Y10 = heating,
Y20 = cooling, Y30 = HR) and one switching output (Q13/Q24 = cooling). It allows for
control sequences using both operating actions, for dampers and HR equipment. Both
operating action and control sequences are adjustable (DIL switches no. 4 to 7).

The basis used for compensation are the setpoints selected on the controller. These
basic setpoints can be shifted as follows:
• Compensation of the controller setpoint in dependence of the outside temperature
(terminal B4); with this function, summer/winter compensation is integrated in the
controller; the compensation characteristic is adjustable
• Compensation by means of an active or passive setting unit, either as an absolute
setpoint or in the form of setpoint shifting via signal input "Z"
• Compensation across the entire setpoint range from an L&S building automation
system via the FLN bus, LON/BACnet bus or LPB bus communication card,
depending on the respective system

This function is intended to make optimum use of the cooling energy supplied to the
plant. Based on the measured differential of outside and room or extract air temperature, the plant is operated either with reduced amounts of outside air or with heat
recovery. The controller then overrides normal control and acts on position signal output
Y30 to position it to 100 % with HR (DC 10 V) or to Y30
min.

During non-occupancy periods, "Unoccupied heating mode" or "Unoccupied cooling
mode" is automatically used, provided enabling took place (can be set for each function)
and the respective preconditions are met. The factory set minimum operating time is 30
min (adjustable from 0 to 12 h).
"Unoccupied heating mode" becomes active when the set supporting level for heating
(adjustable from 0 to 30 °C) is reached. Heating is provided until the room or extract air
temperature exceeds the supporting level by 1 K. In that case, the fans run at speed I or
II (depending on the preselected speed). Outputs Y20 and Y30 with operating action " \ "
are disabled (0 %).
"Unoccupied cooling mode" becomes active when the set supporting level for cooling
(adjustable from 20 to 50 °C) is reached. Cooling is provided until the room or extract air
temperature drops below the supporting level by 1 K. In that case, the fans run at speed
I or II (depending on the preselected speed). Outputs Y10 and Y30 with operating action
" \ " are disabled (0 %).
During non-occupancy periods in the summer, this function is automatically activated if
– the function has been enabled
– both the room and the outside temperature exceed their adjusted limits, and
– the difference between room and outside temperature exceeds the set value.
If the function is activated, cool outside air is drawn into the building. In that case, the
fans run at speed I or II (depending on the preselected speed). Outputs Y10, Y20 and
Y30 with operating action " \ " are disabled (0 %). The factory set minimum operating
time is 30 min. It is adjustable (from 0 min to 12 h).

For ventilating and air conditioning plants using hot water heating coils:
All values for frost protection (response temperatures, setpoints, P-bands, and integral
action times) are preset and can be changed. The temperature is acquired either in the
water circuit or at the air outlet of the hot water heating coil.
The protective actions are the following:
• Continuous opening of the heating valve, activation of the hot water circulator
• Deactivation of the fan or closing of the air dampers
• Maintaining the temperature when the fans are deactivated (only on the water side,
setpoint "Standby controller")
• Fault status signal when there is risk of frost
Use of the following sensors is a prerequisite:
QAE21.9 or QAD22 for frost protection on the water side.
QAF63.2, QAF63.6 for frost protection on the air side.

This function enhances comfort and optimises energy consumption in rooms with
varying occupancy levels. An integral CO
2
/VOC controller reduces the CO2 or
CO
2
/VOC concentration in the room. The P-band, the switching values for the fan
speeds, and the design value at full occupancy are adjustable; the switching differential
is 160 ppm. Using the sensors connected to signal inputs Z, B1 and B2, the controller
acquires the actual temperature and CO
2
values. If CO2 or CO2/VOC concentrations in
the room exceed the switching value of fan speed I + ½SD, the temperature controller is
activated and the fan runs at speed I. The temperature controller maintains the preselected setpoint (Comfort or Economy). If CO
2
or CO2/VOC concentrations increase
further, fan speed II is activated. Between this function and the step output of the
scheduler program, maximum value selection takes place, with both functions having
the same priority. In the case of systems with recirculated air dampers, damper control
is activated also. Here, Y30 minimum limitation, recirculated air start-up mode, and the
frost protection controller with a higher priority act on the Y30 control signal.

Integral limit controller for HR equipment such as thermal wheel type heat exchangers,
plate heat exchangers, and glycol circuits: Setpoint, P-band and integral action time are
adjustable. The limit controller is active only when the plant is in operation (fan speed I
or II).
Using the sensors connected to signal inputs Z, B1 and B2, the controller acquires the
actual temperatures. The manipulated variables delivered by the integral limit and
temperature controllers are compared with one another with the help of a priority
selector which selects the manipulated variable with the smallest value (minimum
selection). This manipulated variable reduces the output of the HR equipment. Since a
certain amount of heat is not now available from the HR equipment, the balance is
delivered by a downstream air heater battery (terminal Y10).
An additional sensor must be installed if this function is used. Three temperature values
(temperature behind the heat recovery equipment, outdoor air and extract air temperatures) 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 103 to 111, set DIL switch No. 2 to the left (ON).
The efficiency calculation acts as a fault indicator, for example, for defective, polluted or
incorrectly connected heat recovery equipment.
This function (display/alarming) is supported by the integration solutions FLN (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 start-up mode is only used with the heating sequence Y30 with operating action "/"
(plants using recirculated air dampers). On plant start-up, either supply air temperature
control or one of the two cascade control modes is activated.
The period of time for start-up mode can be set from 0 s to 60 min. During this time, the
cooling sequence (Y20) is disabled and the hot water circulator (Y10) is activated. The
plant operates with 100 % recirculated air (pre-purging).
In the case of plants that use outside sensors, this f unction becomes active only at
outside temperatures below 15 °C.
In the case of plant start-ups initiated by "Unoccupied heating mode", "Unoccupied
cooling mode" or "Night purging", this function remains inactive.
Plant operation can be controlled from the following locations:
Manual switch (operating level 1: buttons 1 to 4), communication (FLN bus), "External
switch" (E7, E8), "Extended operation" (E7, E8), scheduler program, "Demand controlled ventilation", "Unoccupied heating mode", "Unoccupied cooling mode", night
purging, fault, commissioning.
• From an external switch:
The functions of the manual switch on the RWI65.02 (operating level 1, buttons 1
to 4) can be provided by a 4-step rotary switch with two levels.
• By the function "Extended operation":
When a pulse (of at least 3 s) is fed to E7, the plant is operated at fan speed I;
When a pulse (of at least 3 s) is fed to E8, the plant is operated at fan speed II.
• Scheduler program:
The scheduler integrated in the RWI65.02 facilitates the setting of four switching
times per day; each switching time can be assigned a fan switch position (off, speed I,
or speed II) and a setpoint pair (Economy and Comfort); the settings are made on
operating level 3.
• Summer-/wintertime changeover
This function prevents freeze-up of the hot water heating coil at low outside
temperatures (especially in plants that use on/off dampers).
The period of time during which preheating is active can be adjusted from 0 s to 10 min.
When the plant is switched on, only the hot water circulator (Q13/Q14) initially is
activated while the hot water valve (Y10) is fully open.

To protect the plant, fan speed II is disabled when outside temperatures are very low.
The outside temperature at which this function is activated depends on the set value
(adjustable from
−50 °C to +150 °C). To prevent the controlled system from oscillating
at greatly varying outside temperatures, the RWI65.02 operates with a fixed hysteresis
of 2 Kelvin.
This function is used in connection with outside air handling to save energy (predominantly in rooms with low occupancy levels).
The damper sequence (Y30) with operating action " / " is not implemented as a control
sequence. During plant operation, the damper is preset to a fixed position. The fixed
value of the manipulated variable for the air dampers is adjustable from 0 to 100 %
(Y30 minimum limitation).
• For the hot water pump (DIL switch no. 8 must be in position "Hot water heating coil")
To avoid damage during plant off times, there are three settings:
– The pump is activated permanently;
the pump is activated for 30 s at 24-hour intervals after the last operation, or
– The pump runs continuously when the outside temperature is below 5 °C; the
minimum pump running time (adjustable from 0 s to 30 min) is maintained
– The pump is periodically activated, i.e., the pump is activated for 30 s after the last
operation according to the selected time (adjustable from 5 min to 24 h)
• For the chilled water pump
To avoid damage during plant off times, it is possible to select periodic pump run. If
this function is enabled (selectable), the pump is activated for 30 s every afternoon at
15.00.
• Forced run-up
The fan is always started via the first speed. If the second s peed is selected right from
the start, the first speed is first activated.
Switching to the second speed takes place only when the set time has elapsed
(adjustable from 0 to 5 min).
• Rundown time
When switching down from the second to the first speed, the RWI65.02 deactivates
the second speed, and the first speed is activated only when the preset time has
elapsed (adjustable from 0 s to 5 min).
• In plants using hot water heating coils:
– Continuous checkback signals on the operational status of the plant and on the
status of the hot water circulator, based on the signals received from supervisory
elements such as flow switch and overload protection
– Continuous supervision of risk of frost
– Switching on and off depending on the selected alarm priority ("A" or "b")
• In plants using electric heater batteries:
– Continuous checkback signals on the operational status of the plant and,
especially, on that of the electric heater battery, based on the signals received from
supervisory elements such as flow switch, overload and overtemperature protection
– Switching on and off depending on the selected alarm priority ("A" or "b")
• In plants with heat recovery systems
– Continuous efficiency evaluation
• In plants using chilled water cooling coils/chillers:
– Continuous checkback signals on the operational status of the plant and on the
status of the chilled water circulator or chiller, based on the signals received from

Depending on the 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. Depending on the priority coding of
contact output F91 ("A" and "b" or "A" or "b"), the fault status signal can also be passed
on to F91 as a common fault status signal.
For each status input, the priority of the fault status signal ("A" or "b") can be selec ted.
Each of the status inputs E1 through E6 can be matched to the type of contact of the
respective signal element (N.O. or N.C. contact).
For status inputs E2 and E6, alarm delays to prevent false alarms are also available.
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 F91 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.
For the effects of the fault status signals at the outputs of the RWI65.02, refer to the

The controller consists of a controller insert and the 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 loosened.
An EEPROM stores all setting values. In the event of a power failure, the setting values
are retained for an unlimited period of time. The reserve for weekly scheduling (typically
48 hours) is contained in the controller insert. As a result, the insert can be removed
from its base without affecting the actual time settings.
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.
The RWI65.02 is operated from four operating levels: information level, setting level,
scheduler program level, and commissioning level.
When the front door is closed, the display shows the following information:
Selection of operation (black pointer), manipulated variables, temperatures, weekday,
time, and status information.
The following settings can be made (if not disabled): operating mode (Automatic, fan
speed II, fan speed I, Standby), time of day, weekday, and daylight saving or standard

After opening the front door, operating card 2 can be accessed: the 10 lines of the front
page (operating level 2) show the setting and display options required for operation.
With the exception of lines 5 and 8, the values can be readjusted when operating level 2
is active.
Line 5 displays the actual setpoint of heating (black pointer).
After pressing button 5, the actual setpoint of cooling (no black pointer) is displayed.
When pressing both buttons at the top (lines 1 and 2) simultaneously for two seconds,
the scheduler program level appears. The relevant text is located on the rear of
operating card 2.
Closing the front door automatically reactivates operating level 1.

The RWI65.02 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 RWI65.02 requires no re-commissioning, but only bus
registration for data exchange on the network.
Eighty percent of the plastic materials used can be recycled. In place of NiCd batteries,
the controller has a super capacitor which requires replacement every two years and
improves operating safety and environmental protection.
The controller requires AC 24 operating voltage. The transformer must be suitable for
safety extra-low voltage (SELV), 100 % duty, and must have separate windings.
Fuses, switches, wiring and earthing must comply with all local safety regulations.
The limitations cannot be used as safety functions. These always require separate
safety devices.
All important variables required for commissioning −if known at the time of planning−
must be indicated on the plant documentation (connection diagrams, etc.).
For additional information on the RWI65.02, please refer to the Reference Manual,
ordering no. CM2Z3204E. It contains application examples, detailed function
descriptions, a data point list for commissioning, safety notes, etc.
The controller has been designed for wall mounting (in an open space or inside a
control panel) or flush panel mounting (control panel front, console, etc.). Observe the
permissible ambient conditions. Begin by mounting and wiring the base. The cables
inside the base must be accommodated so that you can easily fit the card.
Secure fixing screws only after commissioning.
The controller is supplied complete with mounting instructions.
For commissioning, the Reference Manual, ordering no. CM2Z3204E, is required.
When commissioning the plant, check all functions of the controller and of the
communication card (if present) as well as the wiring of the connected units.

2) Integral action time (Tn) = 0 s means: P-control for the respective control sequence
Integral action time (Tn) > 0 s means: PI-control for the respect ive control sequence
3) Only when the RWI65.02 is configured for an electric air heater battery.
During the overrun time, the fan runs at speed I. On completion of the selected overrun time, the fans
are switched off and the outside air dampers closed
4) Period of time during which the plant - after arrival of a pulse (> 2 s) at E7 or E8 - shall operat e.
When set to 0 min, the plant is switched on or off the moment the signal arrives at E7 and E8 (external
scheduler) (only in Automatic mode and when the internal scheduler has switched off or is permanently
deactivated)
5) Period of time during which the plant may operate with 100 % recirculated air (after plant start-up)
6) If operating level 1 is locked (data point value = On), it is not possible to change any values for t wo
minutes after closing the front door (except i on: daylight s aving/standard time changeover).
Enabling by reopening the front door
7) The display shows the actual program number (software version)
8) Must be set if the controller is equipped with a communication m odule.
If no communication module is used, the value set has no effect on the RWI65.02
If the RWI65.02 is equipped with the AZI65.3 LPB communication card, the comm unic ation address
becomes the LPB device number with a range of 0 to 16 and a factory setting of 0.
If the
RWI65.02 is equipped with the AZI65.1 FLN communication card, the valid address range
is 33 to 126.
9) Counted are the number of fan operating hours.
The reading can be reset either to zero or to the former value. Proceed as follows:
1. Press function button 10 (line 10)
2. Press setting button "
−" if the meter is to be reset to zero, or setting button "+" if the meter is to be
reset to the former value
3. To confirm resetting, press function button 10 again.

11) The setting of a minimum running time avoids too frequent ac tivation/deactivation of the c irculator
12) To avoid unnecessary faulty alarms, the fault status s ignal c an be delayed
13) Af ter a power failure and subsequent power restoration, it may be necessary to bring the controller back
into operation with a certain delay. This is to make certain that after a power failure, all plant elements
connected to the same mains network are not switched on at the same tim e (peak loads)
14) To protect the plant, the second fan speed is disabled at very low outside temperatures. In that case,
only the first fan speed is enabled. To avoid unneces s ary fan s peed changes when outside
temperatures greatly vary, a hysteresis of 2 K is us ed
15) The cooling signal is released above the set outs ide air t em perat ure value. In order to avoid sliding on
changing outside temperatures, a hysteresis of 1 K has been integrated.
