2.13 Jumpers
Input and output The table below describes the input and the output of the jumpers.
J1 The function of jumper J1 is to reduce the possibility of thermostat OFF (reduce ON/OFF cycle
compr.).
J3 The function of jumper J3 is to increase the differential for thermo ON.
Item Description
Input ∆Tr Cooling ∆Tr = Tr-Ts
P Tr = indoor unit suction air temp.
P Ts = temp. set by the remote controller
Heating ∆Tr = Ts - Tr
Output Magnetic switch compressor K1M
