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 20 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 2°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 2:  
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-)
