Vent Axia Sentinel Multivent H Unit

Overview

Vent Axia Sentinel Multivent H Unit

Top of the range continuous running mechanical extract system with integral humidity sensor and integral digital control panel, designed for the simultaneous ventilation of separate areas in the home or as a multipoint extraction system for a wide range of commercial applications. The integral humidity sensor increases fan speed in proportion to relative humidity levels, saving energy and reducing noise.

Please note - You can purchase the MEV unit with or without the ductwork on this listing

Further Information

Wiring to the Sentinel Multivent

  • If you want the fan to switch to boost speed when a light is turned on, connect the switched live connection from the lighting circuit to the LS connection on the power supply board. When commissioning the unit, a delay on timer and an overrun timer can be selected and adjusted in the software using the buttons and screen. See Commissioning section on page 6 of this document for details.
  • The switched live output (230V) from any other switch or controller, (such as a simple pullcord or push button switch, humidistat or PIR detector) can be connected to the LS terminal instead of connecting to a lighting circuit.
  • Important: Use 4-core, low voltage, twisted pair, telecoms type cable for accessories (Vent-Axia part number 459931). Connect any outputs from accessories / controls that you want to use to the terminal block on the motherboard. Again, use the cable clamp provided. Remove the knock out from the cover. The connections for accessories on the motherboard are powered by a SELV (Safety Extra Low Voltage) power supply.
  • Controllers or switches that switch a volt-free relay can be connected to the volt-free terminals on the motherboard. When the circuit between the two terminals is closed, (when a connected switch is in the 'On' or 
  • 'Closed' position, for example), the fan will switch to Boost speed. There are no delay on or overrun timers with the volt-free connection as the controller should determine when the fan is running at Boost or Normal speeds. Use the LS connection described above if you want a timer.
  • Multiple controllers or switches can be connected to the volt-free terminals when connected in parallel and the cable lengths are not long.
  • Connecting a switch / relay between the Com and Hi terminals will have the same effect as the connecting to the volt-free connections.
  • The Lo, Hi and Com terminals can be used to connect a three position switch. Connect Com to the common terminal of the switch, Lo to Lo, Low or position 1 and Hi to Hi, High, Boost or position 3. No connection to Normal or position 2 is required. If there is no current to the Lo or Hi terminals on the motherboard, the fan will default to Normal speed.
  • The system address needs to match on the receiver PCB and all transmitter PCBs for any one system. For multiple systems in close proximity to each other, the system addresses need to be different in order to identify which transmitters are controlling which fans. The transmitter PCBs also have a 2-way DIP switch to set the transmitter address. Up to four transmitters can be used to control any one Sentinel Multivent. The transmitter address needs to be different for each transmitter in a system.
  • If a number of different accessories are calling for the fan to run at different speeds, the fan will run at the fastest speed called for.

Humidity Sensor

The integral humidity sensor (Sentinel Multivent H) increases fan speed in proportion to relative humidity levels, saving energy and reducing noise

The sensor also reacts to small but rapid increases in humidity, even if the normal trigger threshold is not reached. This unique feature ensures adequate ventilation, even for the smallest wet room

Night-time relative humidity increment setback feature suppresses nuisance tripping as humidity gradually increases with falling temperature

Controllability

  • Demand Control - enables precise ventilation rate, is set in 1% increments based on property size
  • Integral LCD display allows the installer to select appropriate low, normal and boost speeds to meet demand
  • Manual and automatic control options
  • Integral adjustable overrun timer and delay on timer
  • Plug-n-Play automatic sensor detection
  • Switched live and SELV connections
  • Dry Out setting – Option set at installation, Sentinel Multivent will run on boost for 1 week to assist in removing moisture
  • Switches, co2, Humidity, and room sensors are available
