If installing a remote starter, refer to remote starter
instructions before terminating wires.
A Push/Pull switch, or a 7 Day Timer are available for the
heater. Both are discussed on the following pages. Connect the
operating switch as follows.
The 7 Day Timer has been designed to provide a simple means
to control the operation of the heater system and to include the
capability for diagnostics. This timer connects to the diagnostic
circuit of the heater. The timer then displays any heater fault
codes in three digit number form automatically. The timer allows
for pre-selection of turn on time, up to 7 days in advance, as
well as an option for run times up to 2 hours before automati-
cally turning off. In addition, there is an on/off switch for manual
operation. By default the timer is pre-set by Espar to operate for
two hours. Refer to instructions provided with timer for setting
options.
• Mount bezel into dash and insert timer or use Espar’s
optional mounting bracket and secure to dash.
• Use hardware supplied for connections.
• Connect the switch harness to the connector at the heater
and run harness to switch location. (Harness should be
neatly routed and secured under dashboard).
• Cut harness to length and terminate wires. Attach using
connectors provided.
• Refer to timer instructions for other wiring options.

An alternative to connecting the black wire to
the vehicle ignition accessories “On” circuit
may also be considered for some applica-
tions where extended run times are desired.
Connecting the black wire with the red wire
will enable the heater to run continuously
whether the heater is switched on manually
or through the preset function.
