IMPORTANT NOTICE:
Please read this manual carefully before installing or operating your new air
conditioning system. Be sure to save this manual for future reference.
Signal Cable Wiring Diagram(s) for Multi-Circuit Condenser Units
Note Prior to Installation:
The connection cables must be plugged to the corresponding terminals as shown below. Terminal A on the outdoor unit must be connected with Terminal A on the indoor unit, B to B, and so on.
CAUTION
CROSS-WIRING IS A VERY EASY MISTAKE TO MAKE. ALWAYS DOUBLE CHECK THAT THE
LINE GOING FROM A GIVEN TERMINAL BLOCK IS CORRESPONDING TO THE CORRECT ONE
INDOOR.
Connecting Refrigerant Piping for Multi-Circuit Condenser Units
Note Prior to Installation:
The process for connecting the copper refrigerant lines for indoor and outdoor
are given in the full installation manual. Repeat the process for connection
and leak-checking according to the amount of zones to be installed. All pipe
sets use a 1/4” diameter size for the liquid (smaller) side, but the gas
(bigger) line may require the usage of adapters to convert the 3/8” size to
1/2” or 5/8”. Use the included adapters according to the zone combination to
be installed, and refer to the installation manual for proper torquing values.
Regarding the Scope of this Technical Document
Note Prior to Installation:
This manual is intended to supplement the default User and Installation Manual that is found packaged together with the indoor air handler, when used for installation of a Multi-Zone system. The process to install a multi-split system is nearly identical to single-split, with the addition of some repeated steps, and using the additional details found herein.

- Different models of all available matching indoor units can be combined together in any order to create a multi zone split system, up to a quantity of the number of available circuits.
- Not all available circuits need to be utilized with an attached indoor unit. 66% or higher of the total capacity utilization is recommended.
- Every indoor unit attached to a multi zone system will operate at a random, self-regulated capacity, based on the actual demand it measures from the zone it is serving (Between 30% to 100% of its rated capacity) or turn OFF as needed.
- Outdoor units will also self-regulate their total output capacity, based on the total demand it reads from all of the simultaneously running indoor units at any given moment, up to its maximum rating capacity.
- With multi-split systems, the total demand from the outdoor unit, will seldomly exceed 75% of the total available capacity of the combined indoor unit group due to load fluctuations of each indoor unit. Therefore, total attached indoor unit capacity can be selected up to 133% of the supporting outdoor unit’s rated capacity.
- Although very seldom, if the total demand from the combined group of indoor units exceeds the rated capacity of the outdoor unit, the capacity of each indoor unit will be attenuated accordingly.
- For high demand applications, max loading limits may need to be reduced up to 20% to avoid underperformance risks during some extreme conditions.
- The BTU order of attached indoor units has no effect on performance.
Anchoring the Outdoor Unit
The outdoor unit can be anchored to the ground or to wall-mounted brackets. The following is a list of different outdoor unit sizes and the distance between their mounting feet. Prepare the installation base of the unit according to the dimensions found below:
Pioneer WYT Series Multi Split MODEL/Type (Circuit/Series)| D|
E| F| G| H| I| K| M

| 910 mm 35-13/16 in.| 340 mm 13-3/8 in.| 600 mm 23-5/8 in.| 400 mm 15-3/4 in.| 375 mm 14-3/4 in.| 80 mm 3-1/8 in.| 45 mm 1-3/4 in.
If installing the unit on the ground or on a concrete mounting platform, do
the following:
- Mark the positions for four expansion bolts based on dimensions in the “Unit Mounting Dimensions” chart.
- Pre-drill holes for expansion bolts.
- Clean concrete dust away from holes.
- Place a nut on the end of each expansion bolt.
- Hammer expansion bolts into each hole.
- Remove the nuts from expansion bolts, and place the outdoor unit onto the bolts.
- Put washers onto each expansion bolt, then replace each of the nuts.
- Using a wrench, tighten each nut until snug.
WHEN DRILLING INTO CONCRETE, WEAR EYE PROTECTION AT ALL TIMES
Allowable Connected Piping Length and Elevation Differences
Note Prior to Installation:
When installing multiple indoor units to work with a single outdoor unit, ensure that the length of the refrigerant pipe and the drop height between the indoor and outdoor units meet the requirements illustrated in the following diagram:
Unit: m/ft.
| Unit Type | 2 Zone | 3 Zone | 4 Zone |
|---|---|---|---|
| Max. length for all rooms | 30/100 | 50/165 | 60/200 |
| Max. length for one indoor unit | 20/65 | 25/80 | 25/80 |
| Max. height difference between indoor/outdoor unit | 15/50 | 15/50 | 15/50 |
| Max. height difference between indoor units | 30/100 | 30/100 | 30/100 |
Rebalancing Refrigerant Levels Based on Combined Piping Length
For installations with connected lengths beyond standard, charge additional R410a based on the below:
| Unit Type | Pre-Charged For: | Amount of Refrigerant to Add: |
|---|---|---|
| 2-Zone | 15/50 (Total Attached) | 20g x (L1+L2-15M) |
| 3-Zone | 23/75 (Total Attached) | 20g x (L1+L2+L3-23M) |
| 4-Zone* | 30/100 (Total Attached) | 20g x (L1+L2+L3+L4-30M) |
(L1+L2+L3+L4-100ft)
Unit: m/ft. * For any 24K BTU air handlers attached, let L for that length equal 2L.
The design and specifications of this product are subject to change without prior notice as development continues. Consult with the sales agency or manufacturer for details. Refer to the equipment nameplate for all other applicable specifications.
