2. Intruduction
1. The MCRP 054 weather monitoring unit is used to control the
operation of actuators in the MCR-PROLIGHT and MCR PROLIGHT+
vents or in ventilation windows which should be closed in wind or rain.
2. To the weather monitoring unit smoke exhaust control units,
ventilation control units or electromechanical actuators powered by
230 V or 24 V voltage.
3. The closing signal is generated on the basis of readings from a WM1
wind sensor and the RS1/RS2 rain sensor.
4. Output: the device has four switches which are activated in the event
of wind/rain or when mains voltage is lost. The switch remains
activated for a pre-set time after the rain/wind has ceased.
5. The value of rain intensity which activates the alarm can be adjusted
by the user (drizzle – heavy rain).
6. The value of wind force which activates the alarm can be adjusted by
the user - from a gentle breeze (about 5 m/s) to a gale (about 15 m/s).
7. Additional input for a vent position sensor (the circuit is closed when
the vents are open) makes it possible to optically control the vent
status.
8. The device is equipped with the optical signals to indicate the
following status:
•230V~ power supply green LED
•“Wind” alarm red LED
•“Rain” alarm red LED
•“Vent open” signal amber LED
9. The device is equipped with the wind speed indicator – a line indicator
consisting of 7 amber LEDs and one red LED (for wind speeds over
15 m/s).
10. Wall-mounted plastic housing, H x W X D: 180 x 180 x 75 mm;
protection class IP54, colour: light grey (~RAL 7035), leads outlets
either on top or at the rear of the housing.
11. It is possible to connect the weather monitoring unit to a remote
control module which contains optical indicators and potentiometers
for setting the desired sensitivity of the wind/rain sensors.

3. About the MCRP054 weather monitoring unit
Fig. 1 Monitoring unit’s front panel.
On the front panel, there are LEDs which indicate the status of the
control center:
# Description Color Function
1 POWER SUPPLY green indicates presence of power
supply
2 WIND red wind alarm
3 RAIN red rain alarm
4 VENT OPEN amber indicates that smoke vents
(windows) are open
5 WIND SPEED 7 x amber
1 x red wind speed – LED line indicator; scale from about
0 m/s to about 15 m/s
The interior of the weather monitoring unit is shown in Fig. 2.
At the bottom left section of the unit’s PCB, there are two
potentiometers (1,2).
Potentiometer 1 is used to set the sensitivity of the rain sensor:
from a drizzle (far left) to a heavy rain (far right).
Potentiometer 2 is used to set the sensitivity of the wind sensor:
from 5 m/s (far left) to 15 m/s (far right).
Above the potentiometers there are two jumpers: H2 (3) and H3
(4). They are used to switch the weather monitoring unit into the remote
control mode:
remote control mode
local control mode (factory settings)

Fig. 2. View of the unit’s interior.
At the left edge of the board, there’s a set of time coding jumpers
H1 (5) used to code the desired time during which the alarm will remain
on after the cause of the alarm (i.e. wind or rain) has ceased:
Minimum alarm duration
4 minutes
6 minutes
8 minutes
10 minutes
Along the top edge of the module's PCB there are terminal strips
(6) which are used to connect the elements of the system:
Description Function
P1 … P4 input for remote control module
P5 input for vent opening sensor
P6 … P7 input for wind/rain sensor
P9 output 1 from the unit (switch)
P10 output 2 from the unit (switch)
P11 output 3 from the unit (switch)
P12 output 4 from the unit (switch)
P13 auxiliary output 230 V, 50 Hz, max 5 A
P14 power supply input 230 V, 50 Hz
On the board there is an circuit breaker FS1 (7) - 125 mA quick.
PW1 contact (8) is used to connect the indicator board mounted in
the unit’s cover.

MCRP 054 is a maintenance-free device. It requires uninterrupted
230 V mains power supply. Should there be power outage caused by
mains failure, the unit will generate the vent closing signal on output
terminals.
3.2. Alarm
The wind/rain sensor will automatically close smoke vents (or
prevent the vents from being opened by using the ventilation
pushbutton) if the wind or atmospheric precipitation is too strong/heavy.
When the weather monitoring unit is in the alarm mode, the red
LED will light up on its door, and the alarm signal will be generated on
output terminals.
In the alarm mode, the NO contact is open and NC contact is
closed with the COM contact.
The alarm will switch off automatically when the factor which
released the alarm ceases, after a period of time set by adjusting the
H1 (5) jumpers.

4. Warranty terms and conditions.
1. MERCOR SA gives twelve-month warranty for the purchased equipment, unless the "delivery
contract" or "delivery and assembly contract" stipulates otherwise.
2. If during the warranty period any fault resulting from a latent defect in equipment occurs,
MERCOR SA undertakes to eliminate the fault within 21 days from the notification date. In the
