Transformer

Heaters are normally controlled by thermostats. Line voltage thermostats are wired directly (see Figure 18a), the recommended 24V thermostats use a relay (see Figure 18b). Heaters must be grounded in accordance with the National Electric Code ANSI/NFPA - 70 - latest version. Heaters may also be controlled with a manual line
