Consultant Specification
Specification
The unit shall consist of a body manufactured in powder coated sheet steel. The unit shall be fully insulated using high quality EPP to maintain excellent thermal characteristics and prevent shrinkage over time. It shall have EC motors with sealed for life bearings. The fans impellors should be low pressure centrifugal type with backward curved blades within ABS scroll housing and flow ring to provide accurate pressure measurement and incorporate a flow grid to optimise the airflow into the fan. The heat exchanger shall be a diamond shaped multi-plate, counter flow design constructed from Polystyrene with laser welded joints and shall retain up to 96% of the temperature differential of outgoing air with the option to upgrade to an enthalpy heat exchanger for latent and sensible heat transfer plus moisture recovery negating the need for a condensate drain.
The unit shall contain filters manufactured from material which has been tested to a minimum of ISO Coarse (G4) standard with the option to upgrade to ISO ePM1 (F7) or activated carbon ISO ePM10(M5) to remove smells. The filters shall be pleated to reduce the pressure drop and required cleaning time. The unit shall have 180 mm duct connections, and be suitable for vertical wall mounting or floor stand with the ability to allow left or right hand configuration through the unit's software alone no mechanical reconfiguration shall be required. Integrated modulating preheater options shall be available to regulate its output to enable balanced ventilation with external air temperatures -10°C.
The unit shall have a 100% full summer bypass using an in-line modulating mechanism to provide filtered supply air 365 days of the year, even under bypass conditions. It shall provide fresh filtered air to aid night time cooling and prevent condensation within the supply pipework, regardless of the external air temperature. The unit shall contain a temperature sensor for each air stream to ensure correct and logical operation of the bypass damper by evaluating differential as well as absolute temperature to maximise the opportunity for free cooling. The unit shall control air flow to react to prolonged, sustained increased pressure drops to best achieve the commissioned flow rate even when filter degradation occurs. Airflow should not react to short term `wind gusts' to avoid nuisance running.
The unit shall be constructed to have a removable cover to allow full maintenance access. The removable cover shall enable access to the supply/extract fan, heat exchanger and access to electrical connections. The motors shall be suitable for removal without the requirement for the unit to be removed from situ and be available as spare parts for a minimum of 10 years even after ceasing manufacture of the unit.
The unit shall conform to LVD and EMC standards and be CE Marked in addition to having an EU compliant energy rating label (SEC) with a minimum grade of A. The unit shall conform to UK Electrical Equipment (Safety) Regulations and Electromagnetic Compatibility Regulations and be UKCA Marked. The unit shall be manufactured by Zehnder.
Operation
The supply and extract unit shall be a ComfoAir Q manufactured by Zehnder and shall be suitable to mount on a floor stand, wall or in a cupboard in accordance with the specification.
The fresh filtered air from outside shall be supplied to each of the habitable rooms and pre-heated by the warm extract air from the wet areas, such as kitchen or bathroom, via the plastic counter flow heat exchanger. The unit shall vary its speed of the EC motors automatically when it receives a signal from one of the inbuilt sensors or via external switches.
The unit shall have the ability to adjust and commission the supply and extract motors independently via the front mounted in-built LCD interface. The motors shall both automatically adjust independently to the system pressure to achieve the input flow rate.
Controls
All ComfoAir Q units shall contain the following functions within the unit pre-wired and factory fitted by the manufacturer:
· Dial-a-duty motor control · 4 Variable speed flow rate set points · Automatic filtered modulating summer bypass with timed manual override option · Heat exchanger frost protection · Commissioning wizard to enable commissioning of the unit · Integral service, fault and operation indicators · Control panel PIN protection · Tool free filter access · Humidity sensors to operate the unit in response to humidity spikes above natural background humidity
levels as opposed to a single threshold humidity point to activate the high set point · Automatic passive boost for night time cooling · Variable overrun timer relative to high speed activation period
ComfoAir Q 600
Consultant Specification
All ComfoAir Q units shall contain the following options when combined with relevant ancillaries: · BMS compatibility via KNX protocol option (ComfoConnect KNX C) · Wi-Fi connectivity option (ComfoConnect LAN C) · RFZ wireless connectivity option (RF-PCB or ComfoSense C 67) · Switched live input option (Option Box V2 Lite) · Volt free contact option (Option Box V2 Lite) · 0-10V input option (Option Box V2 Lite) · Pre-heater frost protection option · Post-heater control option (Option Box V2 Lite) · Control input for single or multiple capacitive touch speed controllers with 7 day programmer capabilities
(ComfoSense C 67) · Control input for single or multiple 4 speed manual/auto controller with filter alert (ComfoSwitch C 67) · Control input for single or multiple CO2 sensors with combined 3 speed manual controller (CO2 sensor
