STRAP - ON RETURN WATER
TEMPERATURE SENSOR
OPERATING PARAMETERS:
Measurement: from -30°C to +110°C,
Measurement accuracy: ±0,5 K.
Measuring element: PT1000,
output signal: resistance.
Protection rating: IP67.
Designed for DN 20 - DN 80 pipes;
(Outer diameter from 20 to 88 mm).
FUNCTIONS AND APPLICATION:
Functions and application.
Protection of maximum
return water temperature.
DIFFERENTIAL PRESSURE SWITCH
OPERATING PARAMETERS:
Measurement: 40 ÷ 400 Pa
(class G4 ÷ F7 lters).
Rated operating voltage:
250 V AC (Imax = 3 A).
Output signal: voltage
free contact NO or NC.
Number of cycles: 1 million of cycles
(in temp. of 60°C).
Protection degree: IP54.
Operating environment:
from -15°C to +60°C.
FUNCTIONS AND APPLICATION:
Control of the lter’s contamination
level by measuring the permissible
air pressure difference in front of
and behind the lter.
CONSTRUCTION:
A membrane coupled with
a mechanical system which reacts
when the acceptable pressure
difference is exceeded, and,
as a result, switches electrical
contacts (lter contamination signal
or fan unit operation).
Housing: ABS,
ANTI-FROST THERMOSTAT
ON AIR SIDE
OPERATING PARAMETERS:
Maximum temperature,
measurement: from -18°C to +15°C.
Set point of the anti-frost signal:
+5°C (manufacturer).
Rated operating voltage:
30 V DC, 230 V AC.
Output signal: dry de-energized contact.
FUNCTIONS AND APPLICATION:
Protection of the water heater
against freezing is based on the
measurement of the minimum
allowable temperature of the air
ow behind the heater.
If the minimum limit for air
temperature is exceeded, the signal
sent to the controller triggers
the closure of the damper at the inlet
to the unit, switches off the fan
and opens the water valve at its
maximum ow.
CONSTRUCTION:
Measuring element.
2 m long capillary lled
with refrigerant.
The thermostat has adjusting
screws for the proper setting of
the allowable minimum operating
temperature and the temperature
of the re-powering of the system
(hysteresis).
Housing: composite.
The capillary of the thermostat should
be installed in the area of the lowest
temperatures of the medium that supplies
the water heat exchanger.
OVER - HEATING PROTECTION
THERMOSTAT
CONSTRUCTION:
A bimetallic element installed inside
a metal housing.
FUNCTIONS AND APPLICATION:
Protection of the electric heater
against excessive temperatures
above the limit - switching off the
heater and its automatic activation
when the temperature drops
by the hysteresis value.
The element is part of the electric
heater’s standard equipment.
OPERATING PARAMETERS:
Temperature to signal overheating
condition: 65°C.
Switch-off hysteresis value: 22 K.
Output signal: dry de-energized contact,
(change-over contact).
Rated operating voltage:
20 V DC, 230 V AC.
ON-OFF AND ON-OFF/S
- ELECTRIC AIR AMPER ACTUATOR
AND ELECTRIC AIR DAMPER
ACTUATOR (with return spring)
CONSTRUCTION:
Mechanical system with an electric
motor tted in the housing.
FUNCTIONS AND APPLICATION:
Opening or cutting off the air ow
in the air handling unit:ON/OFF
actuator.
Adjustment of mixing ratio for air
supplied into and exhausted
from a room (recirculation):
0-10 V actuator.
For air handling units tted with
a water heater the air damper
actuator has a built-in “return”
spring - the air damper closes
in the absence of voltage supllying
the AHU.
OPERATING PARAMETERS:
Control type: two-point,
closed/open 0 - 100%.
Supply voltage: 24 V AC/DC.
Input signal: ON/OFF.
Torque: 16 Nm, angle of rotation: 90°.
Protection degree: IP54.
Operating environment:
from -20°C to +50°C.
