Operating instructions

The 7 Day Timer has been
designed to provide a simple
means to control the operation
of the heater system and to
include diagnostics capability.
This timer connects to the diag-
nostic 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
adv
ance, as well as an option for
run times up to 2 hours before
automatically turning off. In addi-
tion, there is an on/off switch for
manual operation. By default the
timer is pre-set by Espar to oper-
ate for two hours.
1 Mount bezel into dash and
insert timer or use Esparí s
optional mounting bracket and
secure to dash.
2 Use hardware supplied for
connections.
3 Connect the switch harness to
the connector at the heater and
run harness to switch location.
(Harness should be neatly rout-
ed and secured under dash-
board).
4 Cut harness to length and ter-
minate wires. Attach using con-
nectors provided.
