13. Wall Control and Temperature Sensor Wiring Connections for ESP
Plus Only
SPECIAL NOTES
1. For better responding temperature control it is recommended fitting remote wall mounted or return sensors.
2. Data cable must be 4 core 14/0.20 Screened cable.
3. Remote sensor cables must be screened .

NOTES:
1. When using 2 Wall Controls, the second Wall Control’s on board sensor must
be wired from the indoor board and cannot be looped from the other Wall
Control’s sensor terminal.
2. Use only one 7-day controller with dual (MIMIC LOGIC) controller set up.
NOTES
1. With zoned system using two sensors, such as in domestic applications:
Zone 1 is always assigned to sensor 1 (either Wall Control on board sensor or remote sensor 1).
Zone 2 trough 8 can be assigned to sensor 1 or sensor 2. Selection entry via Wall Control Insert document 9590-3025. When two
sensors are in circuit, the combined temperature readings will be averaged.
2. Non zoned systems using two sensors, such as commercial application:
The combined temperature readings of the two sensors will be averaged.
