Reznor VR Option - Installation - Multiple Heater Control (Options CL31 and CL32) - Manual

Form I-OPT-MH, P/N 102247 R7, Page 1
Applies to: Reznor ® Models LDAP, UDAP, UDAS,
UDBP, UDBS, UEAS, F, B, VR
Description/
Application
These options are designed to permit the control of up to six heaters (one "Primary" heater
and one to five "Secondary" units; see note for LDAP limitations) with one single-stage ther-
mostat or with a time clock and single or multiple single-stage thermostats. For maximum
safety, the multiple control is done in the low voltage circuit. (Interruption of the supply volt-
age is not recommended.) Wiring lengths may not exceed those shown in the table on page
8. DO NOT use these multiple heater control options with a two-stage gas valve or a
two-stage thermostat.
