*To control heating device and provide automatic indoor-
fan operation on heating.
fJumper removed only when separate 24-v transformer power
source is used to power the TSR-01 relay pack
NOTES:
1 Liquid line solenoid valve LLS-A1 is used for solenoid
drop on circuit A Liquid line solenoid valve LLS-B1 is
used for solenoid drop for circuit B.
2 Solenoid drop is a safety feature which prevents refrig­
erant migration to the compressor during the OFF cycle.
It is recommended on all systems and required on sys­
tems where piping exceeds 75 ft (22 9 m) in length
3 The TSR-01 relay pack requires 10 va.
4
Factory wiring is in accordance with NEC; field modi­
fications or additions must be in compliance with all ap­
plicable codes
5 Wiring for field power supply must be rated 75 C mini­
mum Use copper, copper-clad aluminum, or alumi­
num conductors. Maximum incoming wire size for each
terminal block is 500 kcmil
6 Terminal blocks are for external field control connec­
tions Control connections must be class 1 wiring
7 Field-supplied components (IFC, LLS-A1, and
LLS-B1) must have a maximum sealed coil rating of
30 va each (0 25 amp at 120 vac and 0 13 amp at
230 vac) Thermostats must have a minimum pilot duty
rating as follows:

TSR-01 RELAY PACK CIRCUIT BOARD
8 Replacement of factory wires must be with type 105 C
wire or its equivalent
9 Field-supplied liquid line solenoid valves installed at the
evaporator are required on all units
10 Units 38AH094 has 140 va and unit 38AH104
has 130 va of power available for field-installed
accessories
