[2] Aquastat (accessory)
[3] Tee with fill and drain valve
5.2.3 Installing a T&P safety valve (provided by the customer)
▶ Install a listed T&P safety valve that is approved for drinking water
(

¾ ")in the DHW outlet.
▶ The DHW tank must be installed with a new T&P safety valve.
▶ Ensure that the T&P valve is sized no smaller than the rated tank
capacity.
▶ Observe the safety valve installation instructions.
▶ Observe the following when installing the blow-off line for the T&P
valve:
– The blow-off line must be at least equal to the outlet cross-section
of the safety valve.
– Route the blow-off line from the T&P valve directly to an adequate
drain (maximum length 6 ft (2 m) with no more than two 90°-
elbows).
– The blow-off line must terminate at an adequate drain in order to
prevent property damage from spillage.
– Check that the T&P safety valve operates properly at least once
annually.
▶ Never plug the blow-off line. During heating, water may be
discharged for operational reasons at any time.
5.3 Install a tank water temperature sensor (accessory)
or aquastat (accessory)
The DHW tank temperature sensor or aquastat is used to measure and
monitor the hot water temperature of the DHW tank.
5.3.1 Logamatic controller
If a Logamatic controller is used:
▶ Install a DHW tank temperature sensor or an aquastat on the DHW
tank to measure and monitor the hot water temperature.
5.3.2 Installing the DHW tank temperature sensor
▶ Take the tank temperature sensor from the scope of delivery of the
control panel (accessories).
▶ Remove front cover of tank (

Fig. 12 [1]).
▶ To do so, loosen the 4 screws [3] on the sides of the front cover.
▶ Remove front cover of tank [1] and the thermal insulation element
[2].

A conduit is encapsulated in the tank's foam thermal insulation; the DHW
tank temperature sensor can be inserted here.
▶ Insert the DHW tank temperature sensor (

Fig. 13 [1]) into the
conduit [2] at the rear of the tank.
▶ For a type LT300/1: Extend sensor lead with an extension cable (not
included in scope of delivery) and push toward the front.
