• In the case of heat differential /T, the temperature sensor for T condensate must be
connected to the T Warm terminals and the temperature sensor for T steam to the T
Cold terminals.
• In the case of heat differential /p, the temperature sensor for T condensate must be
connected to the T Warm terminals.
