SECTION 10: WIRING AND ELECTRICAL INFORMATION
10.1 Electrical Supply
All heater models need a constant 400 V 50 Hz 3 ø 
supply connected to terminals L
1
,L
2
, L
3
, N & Earth.
Polarity "L
1
 & N" must be correct. The voltage 
between neutral and earth should be 0 and never 
exceed 15 volts.
All heaters and controls must be correctly earthed. 
All external wiring must comply with the relevant 
local codes. Wire specification H05VV-F.
External controls must have a constant 230 V 50 Hz 
1 Ø supply.
An isolator with a contact separation of at least 
3 mm on all poles must be installed adjacent to, but 
not attached to, the DualAir
®
 unit to disconnect all 
supplies to the heater and any remote control.
The final connection to the heater should be made 
by flexible cable or conduit to the main terminal 
block in the control section using 1 mm
2
 cable on all 
models.
All cables entering through the top of the heater 
should be routed via the metal shield to prevent 
inadvertent contact with the flue.

10.2 Remote Control
Roberts Gordon markets a dedicated DualAir
®
 
control that will operate all the available features of 
the unit.
The DualAir
®
 unit requires a 230 V remote control to 
provide a time control and multistage heating/
cooling temperature control. See Page 20, Section 
10.6
.
To operate the modulating gas burner, a further 
input of 0-10 V DC is required with 0V giving 
minimum fire and a 10V giving full fire, wired in 
screened cable (Belden 8451 or equivalent).
10.2.1 Remote Frost Thermostat
When required, connect to terminals 2 and 3 in the 
main terminal block. 
Locate within the heated space adjacent to the most 
vulnerable equipment that requires protection.
See Page 17, Section 10.3
.
10.2.2 Remote Fan Controls
The fan will operate automatically. 
A switch or control wired between terminals 2 & 1 in 
the terminal block will allow external control of the 
fan(s).
The fan may be operated continuously from an 
external control, with the burner/cooling cycling on 
and off.
WARNING
Electrical Shock Hazard
Disconnect electrical power before servicing.
Failure to follow these instructions can result in
death or electrical shock.
