Application
The RT850 Solid State Relay is designed to control a line-voltage
resistive load from a 24 VAC control signal or from signal sources of
4 to 32 VDC. It can be used with fast-commuting thermostat (e.g.
cycles of 15 seconds).
The RT850 is compatible with both mechanical and 2-wire or 3-wire
electronic thermostats (with or without batteries).

Installation
The RT850 must be mounted on a 4" x 4" electrical box.
WARNING:
The relay must be mounted so the heat sink fins are ver-
tical or facing upwards. You should also provide space above the
heat sink for warm air to escape. Disregarding this warning may
result in improper operation of the relay. Refer to the diagram below
for correct mounting guidelines.
All wiring must comply with national and local electrical
code regulations.
The installation should be carried out by an electrician.
Disconnect power before the installation to prevent electri-
cal shock.
Perform the wiring as per figures 1 and 2.
Secure the relay to the electrical box.
Apply power to the heating system.
Verify the installation by increasing the setpoint temperature at
the thermostat to activate the relay (the LED on the relay should
light up).
