42 Installation and Maintenance
4.3.7.1 Installer Connections Key
1. Zone 1 ON/OFF Thermostat:
The On/Off (programmable) therm ostat for either the single space
heating circuit or space heating Zone 1 is to be wired into the
‘Zone 1 ON/OFF Thermostat’ connection. (If a non programmable
room thermostat is used make sure that a heating schedule is set
in the Logic Air controller is s, refer to section
.
2. Zone 2 ON/OFF Thermostat:
For Dual Zone space heating systems, the On/Off (programmable)
thermostat for Zone 2 is to be wired into the ‘Zone 2 ON/OFF
Thermostat’ connection. (If a non programmable room thermostat
is used make sure that a heating schedule is set in the Logic Air
controller is s, refer to section .
3. Link Diagnostics:
Consult the Link Diagnostics manual for further information.
4. Halo Air Interface:
Consult the Halo Air manual for further information.
5. Flow Thermistor - Primary Heating Circuit:
If using a Logic Air No n-Pre-Plumbed Cylinder, the flow 28
mm clip-on thermistor will need to be installed on a section of
copper pipework and secured to avoid it being disturbed.
It is recommended to install insulation to reduce ambient
temperature influence.
The Flow Thermistor is to be placed on the primary flow pipe
(from the Heat Pump) before the circuit separates into the
DHW / CH. This is then to be connected to the control box
via the ‘Flow Thermistor’ connection, use the cables provided
which can be extended if necessary.
6. Return Thermistor - Primary Heating Circuit:
If using a Logic Air Non-Pre-Plumbed Cylinder, the return 28
mm clip-on thermistor will need to be installed on a section of
copper pipework and secured to avoid it being disturbed.
It is recommended to install insulation to reduce ambient
temperature influence.
The Return Thermistor is to be placed on the primary return
pipe (from the Heat Pump) after the circuit combines from the
DHW / CH. This is then to be connected to the control box via
the ‘Return Thermistor’ connection.
7. Header Thermistor
Only used in cascade mode. Refer to Logic Air Cascade
Instructions.
8. Domestic Hot Water Thermistor
When using a Logic Air Pre-Plumbed cylinder, the Domestic
Hot Water Thermistor will be pre-installed as part of the
package. If using a Logic Air Non-Pre-Plumbed Cylinder,
the DHW thermistor will need to be inserted into the sensor
pocket and secured to avoid it being disturbed.
If using a third party DHW cylinder, refer to the
manufacturer’s installation guidelines for thermistor
installation requirements, use the cables provided which can
be extended if necessary.
9. Outside Thermistor (QAC-34)
Refer to Section
4.4.1 Outdoor Sensor Installation
for further
information.
10. Mains supply - Immersion Heater or Backup Boiler
Input connection for a 230V ac mains supply, as per Section
4.3.6 for a 3 kW immersion heater.
ᘐ
CAUTION: This supply must be protected by a
dedicated circuit breaker (16 A - C curve)
OR
If using a boiler backup application, this input connection
is used for a switched live "call for heat" circuit (refer to the
boiler installation manual for wiring details).
11. Immersion Heater or Backup Boiler
Output connection for a 230V ac mains supply, as per
Section
4.3.6
for a 3 kW immersion heater.
OR
If using a boiler backup application, this output connection
is used for a switched live "call for heat" circuit (refer to the
boiler installation manual for wiring details).
12. Faults
If external fault indication is required, it is to be wired into the
‘Fault (EX1)’ connection.
ᘐ
CAUTION: The line voltage is 240V.
13. Tariffs
If Tariff Control is required, it is to be wired into the ‘Tariffs
(EX2)’ connection.
ᘐ
CAUTION: The line voltage is 240V.
14. Logic Air Heat Pump Connections
Connections for both the 230V Mains Power Supply and the
Communication between the Logic Air Monobloc Heat Pump
and the Logic Air Control Box.
15. Overheat Thermostat - DHW Cylinder
When using a Logic Air Pre-Plumbed cylinder, the DHW
Overheat Thermostat will be pre-installed as part of the
package. If using a Logic Air Non-Pre-Plumbed Cylinder, the
DHW Overheat Thermostat will need to be installed in the
sensor pocket (Refer to Section
2.3
for sensor location) and
secured to avoid it being disturbed. It is recommended to
install insulation to reduce ambient temperature influence.
If using a third party DHW cylinder, refer to the
manufacturer’s installation guidelines for thermistor
installation requirements.
ᘐ
CAUTION: The line voltage is 240V.
16. 3-Way Valve
When using a Logic Air Pre-Plumbed cylinder, the 3-way
valve will be pre -installed as part of the package. If using a
Logic Air Non-Pre-Plumbed Cylinder, the
3-way valve will need to be installed and connected to the
control box via the '3-Way Valve' connection and must spring
return to the CH position.
ᘐ
CAUTION: The line voltage is 240V.
17. CH 1 Pump or Valve
The pump for either the single space heating circuit or space
heating Zone 1 is to be wired into the ‘CH1 Pump or Valve’
connection.
ᘐ
CAUTION: The line voltage is 240V.
18. CH 2 Pump or Valve (If applicable)
For Dual Zone space heating systems, the second zone pump/
valve is to be wired into the ‘CH2 Pump or Valve’ connection.
ᘐ
CAUTION: The line voltage is 240V.
