1 Required (RB) J5-4 LTB1-EF Run command to VFD Refer to air handler connections.
2 Required (RB) J5-6 RTEM J7-6 High speed command to VFD

Optional (RB) J10-1
LTB1-R
Power relay board
It is recommended that the air handler
and condensing unit share low voltage
power. If the air handler and condensing
unit have separate low voltage power,
these conductors can be omitted, but
isolation relays are needed on the
remaining control wire conductors.

Optional (RB) J10-2
LTB1-B1
5 Optional (RB) J5-1 LTB1-CD Disable the compressor when
EDC switch activates
If the EDC switch in the air handler will be
utilized for low evaporator compressor
protection, remove the jumper wire [W1
(R)] that connected between the
terminals LTB1-R & LTB1-CD in the
condenser unit. If EDC wired, change the
connection from Terminal ‘H’ (NO) to
terminal ‘L’ (NC).
6 Optional (RB) J5-7 LTB1-H1 Command to enable Heat –
stage 1
Conductor is required only if the air
handler is installed with the electric heat
units. If the electric heat kit is installed,
remove the bypass wires 55A connecting
J2-1 & J2-2 on RTRM (condenser unit) to
enable the electric heat. For two stage
electric heat, remove the bypass wire 49A
connecting J1-3 & J1-6 on RTRM
(condenser unit).
7 Optional (RB) J5-8 LTB1-H2 Command to enable Heat –

1. Remove the existing wire harness from relay board P1 and VFD terminals 61, 68, and 69. This
harness is not used for this pairing.
2. Connect wiring harness WIR010190 and WIR010185 from relay board J11 to VFD terminals 12,
18, 50, and 53. Verify that jumper exists between VFD terminals 12 and 27.
3. Update the following parameters in the TR150 VFD.
a. Change 3-15 from [11] Local Bus reference to [1] Analog Input 53
b. Change 5-10 from [0] No Operation to [8] Start
c. Change 5-12 from [0] No Operation to [2] Coast Inverse
d. Change 8-01 from [2] Control Word Only to [0] Digital and Control Word
e. Change 8-02 from [1] FC Port to [0] None
f. Verify 4-12 is set to 25 HZ
g. Verify 4-14 is set to 60 HZ
h. Verify 6-10 is set to 0.07V
i. Verify 6-11 is set to 10.00V
j. Verify 6-14 is set to 25 HZ
k. Verify 6-15 is set to 60 HZ
