3 GENERAL BOILER INFORMATION
3.1 General
The Intergas Compact HRE OV wall mounted, gas fired boiler is suitable for use in
open vent systems with a heating system feed tank. The appliance is designed to
transfer heat to the water circuit in a CH system and when an indirectly heated
domestic hot water (DHW) storage cylinder is installed, apply heat to the DHW
installation.
The air supply and combustion gas flue connection is as standard prepared for a
concentric 60/100 flue system. The Intergas Compact HRE OV wall mounted gas fired
boiler carries the CE rating and IP44 electrical protection.
The appliance is supplied as standard for natural gas (G20). For usage of propane gas
(G31) the boiler can be modifed by changing the gas metering ring. A gas conversion
kit can be ordered at Intergas Heating Ltd.
Note
Modification of the boiler can only be done by a qualified competent person.
3.2 Boiler controller
An electronic control unit, consisting of a boiler controller and separate ignition module
which is placed on the gas valve, provides direct burner ignition and flame supervision
along with continuous modulation of the burner’s gas supply.
3.3 Parameter list
All boiler adjustments are accessible through the parameter list in the software.
3.4 Heat transfer
Heat transfer to the boiler’s heating circuit is obtained via a primary, gas to water heat
exchanger within a hermetically sealed combustion chamber. A modulated speed fan
blows the gas/air mixture into the combustion chamber and expels the products of
combustion to outside air via an associated flue system.
3.5 Central heating system
An external pump can be connected on terminal X2/7-8, see chapter 13.
3.6 Room temperature control
Room temperature can be controlled by the use of an external room thermostat and
thermostatic radiator valves.
Note
Connection of the room thermostat is dependant on the operating voltage of the
thermostat.
3.7 Integrated clock
The boiler incorporates an integral clock, which allows the setting of central heating
periods (See the User Instructions, ‘Operation and display read-out’ for details) and the
boiler’s control panel incorporates an LED display, which indicates the state of
operation and fault defect codes. When an external controller is used the integral clock
must be set onto c-on (See § 4.4).
Intergas Heating Ltd
11
4 OPERATION
4.1 General
The Intergas Compact HRE OV wall mounted, gas fired open vent boiler is a
modulating high efficiency boiler. This means that the power is adjusted in line with the
desired heat requirement. It is designed to be used in an open vented system with
heating system feed tank.
The appliance is equipped with an electronic boiler controller which, each time heat is
requested from the heating supply, starts the fan, opens the gas valve, ignites the
burner and continuously monitors and controls the flame, depending on the requested
output.
4.2 Central heating mode
When a heating demand is requested (power is on, the timer and thermostat are calling for
heat) the external pump is energised and the boiler will fire automatically. The hot water is
now circulated around the central heating system. When the end of the central heating
demand is reached (the thermostat reaches temperature or the time clock reaches the end
of its set period) the burner will shut down while the pump remains functioning during a
preset period of time to dissipate any excess heat from within the boiler’s heat-exchanger.
After that the boiler will revert to stand-by, waiting to respond to the next heating demand.
4.3 Operating modes
A code on the service display of the operating panel indicates the appliance’s operating
mode.
-
Off
The appliance is out of operation but is supplied with electrical power. No response
occurs to calls for DHW or CH. The appliance frost protection is active. This means that
the external pump operates and the exchanger is heated up if the temperature of the
water present in it falls too far.
If the frost protection is actuated, code
7
is displayed (heating the exchanger).
In this operating mode the pressure in the CH installation (in Bar) can also be read on
the temperature display.
Waiting mode
The LED at the button is lit and possibly one of the LEDs for the DHW comfort
function. The appliance is ready to respond to a request for CH of DHW.
0
Pump overrun of CH
After the end of CH operation the external pump continues to run. The running time is
factory set at the value in accordance with § 10.3. This setting can be changed.
In addition, the pump runs automatically for 10 seconds once every 24 hours in order to
prevent seizing. This automatic switching on of the pump occurs at the time of the last call
for heat. To change the time, the room thermostat setting should be increased briefly at the
desired time.
1
Boiler shutdown when required temperature reached
The boiler controller can temporarily shut down the request for heat. The burner is then
stopped. Shutdown occurs because the requested temperature has been reached.
When the temperature has fallen sufficiently and the anti cycle time has passed the
shutdown is cancelled.
2
Self-test
The connected sensors are checked regularly by the boiler controller. During the check
the boiler controller does not perform any other tasks.
3
Ventilation
When the appliance is started the fan is first brought to starting speed. When the
starting speed has been reached the burner is lit. Code 3 is also visible when post-
ventilation is taking place after the burner has stopped.
Intergas Heating Ltd 12
4
Ignition
When the fan has reached the starting speed, the burner is ignited by means of
electrical sparks. During ignition the code
4
is visible. If the burner does not ignite, a
new ignition attempt occurs after approximately 15 seconds. If after 4 ignition attempts
the burner is not yet burning, the boiler controller goes into fault mode (See § 11.1 ).
5
CH operation
An on/off thermostat, an OpenTherm thermostat, an external sensor or a combination of
the latter can be connected to the boiler controller.
When a request for heat is received from a thermostat, the fan is started (code 3 ),
followed by ignition (code
4
) and CH operating mode (code 5 ).
During CH operation the fan speed and hence the appliance power are controlled by
the boiler controller so that the CH water temperature reaches the desired CH supply
temperature.
If an on/off thermostat is connected, this is the CH supply temperature set on the
display. In the case of an OpenTherm thermostat the desired CH supply temperature is
determined by the thermostat. In the case of an external sensor the desired CH suppply
temperature is determined by the heating line programmed in the boiler controller. For
the latter two, however, the maximum is the temperature set on the display.
During CH operation the requested CH supply temperature is indicated on the operating
panel.
The CH supply temperature can be set between 30°C and 90°C.
4.4 Clock function
The boiler is equipped with a digital clock and offers the possibility to program 4 points in time
to switch from CH off or CH on.
During the “clock active” periods the boiler will respond on CH demands from the room
thermostat. During the “clock inactive” periods the boiler will not respond on CH demands.
When an external controller is used the internal clock must be set onto c-on.
Additionally the following special modes can be chosen:
1. t-on (temporary on).
The boiler will respond to every CH demand from the room thermostat until the next switch moment.
2. c-on (continuous on).
The boiler will respond to every CH demand from the room thermostat without any time limit.
3. OFF.
The boiler will not respond to any CH demand from the room thermostat.
Note
For setting and adjusting the clock see § 9.3 Setting and adjusting the clock functions.
4.5 PC interface
The boiler controller is equipped with an interface for a PC, which can be connected by
means of a special cable and associated Intergas Diagnostic Software (IDS). This
facility allows the behaviour of the boiler controller, the appliance and the heating
installation to be monitored over a longer period.
Intergas Heating Ltd
13
4.6 Test programs
The boiler controller has a facility for placing the appliance in test mode. Activation of a
test program will result in the appliance starting operation at a fixed fan speed, without
the control functions being actuated. The safety functions do remain active. The test
program is ended by pressing the and simultaneously or will end automaticaly
after 10 minutes.

4.7 Frost protection
FROST PROTECTION
To prevent freezing the appliance is equipped with an internal frost
protection. If the heat exchanger temperature falls too low, the burner
switches on and the external pump runs until the heat exchanger
temperature is sufficient. When the appliance frost protection is
activated the symbol code
7777
is displayed (pre heating the heat
exchanger).
If the installation (or a part of it) is in danger of freezing, an (external)
frost thermostat must be fitted to the return line at the coldest location.
This must be connected in accordance with the wiring diagram
(See § 8.2.1).
Note
If the appliance is out of operation (
-
on the service display) the appliance ’s internal frost
protection is still active. However, this means there will be no response to a request for heat
from an (external) frost thermostat.
