7 Day Timer Instructions
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
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 automatically 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.
