General
This Standard specifies requirements for thermostat models intended for line-voltage (120 to 240 V) switching of a controlled resistive heating load. It includes single- and double-pole thermostats that control their load by fast or slow ON/OFF switching. The models covered by this Standard are as follows:
(a) wall-mounted line-voltage thermostats;
(b) built-in line-voltage thermostats (up to 1500 W); and
(c) two-component thermostats.
This Standard's requirements apply only to local zone thermostats; they do not apply to central heating units under the control of a single thermostat or to thermostats used exclusively to control radiant heating systems.
Thermal regulation and power line quality
This Standard specifies performance requirements covering thermal regulation and power line quality. The thermal regulation requirements are based on testing in a dual-climate test chamber. The power line quality requirements establish the level of emissions that may be generated by line-voltage thermostats and the extent of line-voltage thermostat susceptibility to electromagnetic disturbances that can be present on power lines.
Terminology
In CSA Standards, "shall" is used to express a requirement, i.e., a provision that the user is obliged to satisfy in order to comply with the standard; "should" is used to express a recommendation or that which is advised but not required; "may" is used to express an option or that which is permissible within the limits of the standard; and "can" is used to express possibility or capability. Notes accompanying clauses do not include requirements or alternative requirements; the purpose of a note accompanying a clause is to separate from the text explanatory or informative material. Notes to tables and figures are considered part of the table or figure and may be written as requirements. Annexes are designated normative (mandatory) or informative (non-mandatory) to define their application.
Units of measurement
The values given in SI (metric) units are the standard. The values given in parentheses are for information only.
