(Based on System
Voltage
Requirements)
Make sure 7600 outputs do not exceed 7.4A @ 120 VAC. 7600 outputs are not rated for 240 VAC.
7600 will require an additional wire (L2) for operation. Short TW-TR terminals. C1, C2, ZC, and ZR are unused.
Set low limit on 7600 to OFF.
Available operating limit and/or differential ranges may not be equivalent. Compare the settings to the AquaSmart ranges before replacing.
To use with a millivolt system, an appropriate voltage relay with isolated gold plated contacts must be added to switch the millivolt circuit.
