Electric Heating Multi-stage finned electric heating elements complete with auto and manual reset
overheat cut-out protection, phase balanced for increased efficiency.
IMPORTANT A separate mains incoming power supply is required with the electric
heating option.
or
Low Pressure Hot Water
(Cooling Only Units)
A low pressure hot water coil constructed of refrigeration quality copper tube and
mechanically bonded aluminium fins can be factory fitted.
Frost protection is fitted to prevent freezing of the low pressure hot water coil assembly.
Proportional heating control is provided by a factory fitted 3 port modulating valve.
A bypass balancing valve is fitted to aid commissioning and unit operation by creating the
same pressure drop through the bypass as through the LPHW coil.
Phase Monitoring Relay A phase monitoring relay can be fitted; this offers protection for phase rotation, loss of
phase plus under and over voltage control.
Phase Rotation
Protection A phase sequence relay is available for units containing 3 phase scroll compressors, to
prevent possible damage by running the compressor in the wrong direction.
Enthalpy Controls The microprocessor can be programmed to calculate enthalpy values from the
combined temperature and humidity sensors fitted within each unit measuring return air
and ambient air conditions.
Enthalpy sensors will allow the microprocessor control to prevent high humidity fresh air
conditions entering the conditioned space.
Energy Manager Analysis of system energy consumption can be monitored via a dedicated LCD display.
Unit parameters can be adjusted via the unit microprocessor control to affect energy
usage in line with the system needs. With the optional interface card fitted all information
from the energy manager can be monitored from a BMS.
Air Quality Monitoring The main gases detected are, for what concerns the volatile organic compounds (VOC), a
mixture of the following gases; carbon monoxide CO
2
, sulphur water H
2
S, solvent
vapours, alkane vapours, cigarette smoke, car exhaust, air produced by human
breathing, combustion smoke from wood, paper and plastics. Additionally, the problem
detects the concentration of CO
2
from 350 up to 200 ppm.
The VOC mixture is displayed as a % from 0 - 100% via the microprocessor
keypad display.
