Switch 7: Active only if switch 8 is set to Chrono. This
switch determines the number of cycles per hour
that the thermostat will impose on the system,
the options are three 0 minute cycles or six 10
minute cycles.
Switch 6: Allows Celsius or Fahrenheit temperature scaling
to be selected.
Switch 5: Enables or disables a compressor delay timer
which is activated at the end of each cooling call.
This feature need only be used where cooling is
provided by a compressor as opposed to chilled
water. Set to Cmp del if a compressor delay is
required, otherwise leave set to No Cmp del.
Switch 4: Active only if switch 5 is set to Cmp del. The op-
tions are 3 or 4 minutes.
Switch 3: Allows dead-band between heating and cooling to
be set, options are °C or 4°C.
Switch 2: Allows application to set as fan coil or as heat
pump. If heat-pump is selected, the output
normally used to operate the heating valve is
re-assigned to the heat-pump reversing valve,
the compressor stop/start signal for both heat
and cool calls is re-assigned to the relay normally
used to operate the cooling valve.
Switch 1: The function of this switch is dependent upon the
setting of switch :
o
Switch 2 set to Fan-coil: Leave set to TS
o
Switch 2 set to Heat-pump: allows the reversing valve to
be set up to be energised in heating mode (R+), or
energised in cooling mode (R-)
