Beckett Replacement Notes

7600A

The 7600 has no Honeywell EnviraCOMTM Communications port. The diagnostic LED lights are replaced by the 7600’s display.

7600 outputs are not rated for 240 VAC. B1 terminal on 7600 utilizes a 1/4” quick connect. Set low limit on 7600 to OFF.

7600 outputs are not rated for 240 VAC. B2, TW and TR terminals replace TV, T and Z, respectively.

For replacement with the 7600: Turn low limit off so the circulator is controlled directly by the thermostat and ZC is constantly powered.

7600 outputs are not rated for 240 VAC. Remote mount sensor cable needed (Part No.

52120)

Not a suitable replacement if Low Water Cutoff (LWCO) functionality is used.

Make sure 7600 outputs do not exceed 7.4A. Available operating limit and differential ranges are not equivalent.

Make sure 7600 outputs do not exceed 7.4A @ 120 VAC. 7600 outputs are not rated for 240 VAC. Available operating limit and differential ranges may not be equivalent.

Not a suitable replacement if SPDT switch action is required; only break-on-rise available on 7600. Make sure 7600 outputs do not exceed 7.4A @ 120 VAC. 7600 outputs are not rated for 240 VAC.

Beckett Replacement Notes

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. Set low limit on 7600 to OFF. To use with a millivolt system an appropriate voltage relay with isolated gold plated contacts must be added to switch the millivolt circuit.

Requires the addition of a manual-reset high limit. Make sure 7600 outputs do not exceed 7.4A @ 120VAC. 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.

Must conﬁ rm that 7600 VA rating is adequate to meet VA requirements of system. Make sure 7600 B1 output does not exceed 1.25A @ 24VAC (30 VA). 7600 outputs are not rated for 240 VAC. B2, TW and TR terminals replace TV, T and Z, respectively. If damper is used, consult damper manufacturer’s wiring instructions for using damper without damper plug.

Remove switching relay, if used, from the system when replacing the L4081 or L6081 Make sure 7600 outputs do not exceed 7.4A@120VAC. 7600 outputs are not rated for 240 VAC.

Short TW-TR terminals. C1, C2, ZC, and ZR are unused.
