Part Number Coding
The VES HEATLINE Duct Mounted Heater Battery brings wider versatility to existing and new
ventilation installations. Intelligent control options for BMS or LCD room units, plus a
Thyristor (EHB option) /Valve actuator (LPHW option) heater make this the ideal solution to
accurately heat individual rooms. HEATLINE is also both simple to install and maintain.
Duct sizes form a slow as 100 Square/Round on EHB, 200 Square/Round on LPHW. Operating
temperature -20 to 70 ºC.

ensure that access panels are not obstructed in any way and safe working access for
maintenance must be provided in accordance with the Health and Safety, and Building
Regulations. For confirmation of required access please see the appropriate unit outline
drawing.
Consideration must also be given by the installer for adequate illumination of the unit
location in order for safe maintenance. Further consideration should be given to the unit’s
position and secured into place as appropriate. This is especially important with external
mounting as the wind and elements may effect overall stability.

When moving the unit, handle with care and in such a manner
as to avoid damaging the external finish as this may reduce
the ability to reduce corrosion. Units are to be rigged and
lifted using spreaders, taking into account the weight of the
unit, and lifting gear should be arranged so as not to bear on

Duct Installation 6
For sensitive installations, VES can offer a 4 to 20 mA control option.
Important
Fan run on sequence determined by BMS.
Warning
To ensure safety and compliance, please refer to O&M manual for wiring, fan run-on, and
installation instructions.
Warning
6.1 Airflow
Caution The heater can be used for horizontal or vertical airflow. The air should be evenly
distributed across the duct and the minimum air volume as stated on the air heater name
plate must be maintained.
6.2 Thermal
Cutout (Auto)
(EHB option only)
Every heater is provided with a thermal cutout which will break contacts when the duct
temperature rises above 70 °C. This cutout is provided to comply with M & E specifications
and will require removal of the terminal cover to reset.
Supply must be isolated before removing cover.
Warning
N.B. It is very important that all electrical connections are properly made. Elements are
tested prior to dispatch and are within tolerance of ±7½ W of total load. If the elements are
found to be faulty they can be easily removed and replaced. Elements stored in damp
conditions may need drying to attain correct insulation readings - contact VES Andover Ltd. if
in doubt.
6.3 Testing
(EHB option only)
Continued
Supply to Heatline should be 1ph or 3ph and a neutral - refer to name plate for
correct supply.
The heater is fitted with a manual reset high temperature cutout which has NC
(normally closed) terminals and an air flow pressure switch. This is connected in
series with the main contactor coil circuit, to remove power from the heater in the
event of over-temperature or airflow failure. Under no circumstances is this circuit to
be by passed.
Ensure sufficient earth connection to terminal is provided.
The speed controller must not switch off fan independent of control system or
allow airflow to fall below stated volume on the electric heater battery.
Fan run on timer required. Turn off 0-10 V heat demand signal 2 minutes before fan
enable signal.
Separate cables should be installed for 0-10 VDC, Control signal and 24 VAC switched
enable signal in compliance BS7671/2008.

external piping is to be supported independently from the coil. Fluid filters are
recommended.
It is important that water and steam coils are protected against damage from extreme
weather conditions during the winter season. If the water is allowed to freeze in the coil
system, damage may occur potentially bursting pipes and resulting in emergency problems.
Fitting a frost thermostat at the unit inlet and ensuring that boilers run continuously in low
ambient temperatures can help to prevent this.
Heating coils do not cool immediately when the hot water supply is turned off. The residual
heat must be dissipated to avoid damage. The continuous running of the fan after
shutdown resolves this, by operation of a run-on timer; the recommended length of run-on
is 2 minutes minimum.
On HeatLine units, a Low Pressure Hot Water (LPHW) coil will be installed. Coils are normally
suitable for LPHW at 82 °C flow and 71 °C return temperature. LPHW coils are supplied as

the coil connection. The air vent should be at the highest point, with the drain at the
lowest. The coil should be regularly vented so as to avoid potential air locks, resulting in a
fall off of duty.
It is recommended that a check be made as to whether any treatment is required to the
water supply for prevention of corrosion and scaling of the equipment. Information
regarding the necessary action to be taken can be obtained from the relevant Local Water
Supply Authority.
The unit will have been supplied with connections either left or right-hand side looking in
direction of airflow. Please see order acknowledgment for confirmation of this handing.

LPHW units feature a coil connection cover. To access during installation carefully remove
the cover by unfastening the fixings around the cover. Holes have been provided in the
housing base for pipe work entry. Please follow the appropriate manufacturer’s instruction
carefully when fitting a valve actuator. Ensure that the cover and fixings are replaced upon
completion.

Important
It is recommended that the cable entry point should be at the end of the control
section as shown in the figure below.
It is the responsibility of the installer to ensure that a suitable cable gland (giving
adequate protection and strain relief) is fitted, and in doing so also ensure that no

9.3 Mounting and
installation continued
Select the application and the type of control output via the DIP switches before fitting the
thermostat to the mounting plate. After power is applied, the thermostat carries out a reset
during which all LCD segments blink, indicating that the reset was correct. After the reset,
which takes about 3 seconds, the thermostat is ready for commissioning by qualified HVAC
staff. Refer to section 7.4
The control parameters of the thermostat can be set to ensure optimum performance of the
entire system. See page 15 to find out how to set.

9.4 Control sequences
The control sequence may need to be set via parameter P01 depending on the application.
The factory setting is P01= 0 (heating only)
Recalibrate the temperature sensor if the room temperature displayed on the thermostat
does not match the room temperature measured. To do this, change parameter P05.
We recommend to review the setpoints and setpoint setting ranges (parameters P08…P12)
and change them as needed to achieve maximum comfort and save Energy

9.5 Fan control The HLS/HLD unit has single speed fan control only.
The clean fan filter reminder function counts the fan operating hours and displays message
“FIL” to remind the user to clean the fan filter as soon as the threshold is reached. This
does not impact the thermostat’s operation, which continues to run normally.
The clean filter reminder is reset when the operating mode is manually set to Protection
and back. See section 9.1
Clean Filter
Fan operation in
AutoTimer
In Auto Timer mode, the default fan mode is automatic. The fan mode can be changed to
manual by pushing the “FAN” button. The fan returns to the automatic default mode after
each switchover from Comfort to Energy Saving mode and vice versa.
When the electrical heater is switched off, the fan overruns for at least 3 minutes (param-
eter P54 factory set by VES) to avoid over temperature of the electrical heater or prevent the
thermal cutout from responding. In case of fan failure, the thermostat cannot protect the
electrical heater against over temperature. That is why the electrical heater features a
separate safety device (thermal cutout).
Note: For the BMS option the fan run on must be controlled by others

be assigned to one or several days. In this mode, the thermostat automatically changes

When the room temperature is outside the measuring range, i.e. above 49 °C or below 0 °C,
the limiting temperatures blink, e.g. “0 °C” or “49 °C”.
The heating output is activated if the current setpoint is not set to “OFF”, the thermostat is
in heating mode and the temperature is below 0 °C.
For all other cases, no output is activated.
The thermostat resumes Comfort mode after the temperature returns to within the
