NOTES:
1. Standard control steps are listed under the Control Step heading. "Free" additional steps of control are
2. MCA = 1.25 x FLA; for proper wire sizing, refer to Table 310-16 of the NEC (National Electrical Code).
3. Sub-circuits are internal heater circuits of 48 amps or less.
4. Electric heat performance is not within the scope of AHRI standard 430 certification.
5. To avoid damage due to overheating, minimum face velocity cannot fall bellow 350 fpm.
6. Heaters up to (and including) 60 kW have 3 control steps; beyond 60 k, 6 steps are standard.
7. Heater kW offering is controlled by AHUBuilder® program. This table is for reference only.
